It is extremely interesting that you should mention Betty's Angel.
I showed Ken McLean her pedigree and he suggested three things for her.
1 Bring back a BROTHER to Sobbing Sal
2 Duplicate NEW TEARS in the dam of the stud dog
3 Use a SON of NEW TEARS

Ken also suggested that if Betty's Angel had a litter sister that was an ordinary runner then New Tears should be duplicated as the damsire of the stud dog she is put to.

This is an example of what he meant (and I only use Carlisle Jack because he fits the criteria. NEW TEARS is in the position Ken suggested should be utilised.)

or this

CLICK HERE

It is all to do with the position of New Tears in the pedigree of the resultant pups. It has nothing to do with the sire of the stud dog, or the damline of the broodbitch.
It is exactly for this reason that I mentioned earlier about the damsire of the stud dog being all important. Is this why so many stud dogs with an import as their damsire cannot make a great impact at stud? Their damsire (in an important position) doesn't have enough compatible blood in the broodbitches mated to this dog.

As for the El Galo-Betty's Angel mating, this is exactly how New Tears/Ginger/Amerigo Man were bred and they've had a pretty good influence and all could run like the wind.

You will recall I mentioned that if a stud dog that is in-bred top and bottom as in the case of Token Prince to Waverly Supreme 3x3

CLICK HERE
and we have pointed out that for him to be a success, he must be mated to broodbitches with Brother Fox (or his half brother Acacia Park) which we found to be right, then surely it must be the same for a broodbitch.

Have a look at this broodbitch. The great Thelma's Mate

CLICK HERE
you will see she is in-bred top and bottom to a dog called Cinder.
If what is true for Token Prince, is to be true for Thelma's Mate, then the stud dog she is mated to must contain her damsire Sterling in his pedigree somewhere.

And here he is ... the legend Chief Havoc.

Dan, I'll look more into your post.

this sex balance linebreeding sounds very intriguing. However I find it extremely difficult to find convincing evidence.

These are the Australian top dogs for the last 5 years(GD points ranking): CLICK HERE
If you prefer we can focus on the standard distance: CLICK HERE
Which dogs would be adding substance to the theory?

Thanks for explanation, Tomas

PS.taking your example of IM SLIPPY further, wouldnt SLIPPY BLUE have had to become a top sire?

Without going through them all ...
Arvo's Junior
CLICK HERE is sex balanced to both
Brother Fox
(through the female Gravel Rash in the pedigree of Arvo's Express, and the male Walkabout Sid in the pedigree of Arvo's Alarm)
and
Chariot Supreme
(through the male Hay Dinney in the pedigree of Arvo's Express, and through the female Wee Sal in the pedigree of Arvo's Alarm).

PAUA TO BURN
an extremely interesting pedigree
CLICK HERE she is sex balanced to Waverly Supreme and also has a balance of sorts to the half brothers Acacia Park (through a male) and Brother Fox (through two females)
she also has plenty of sex balances to Temlee

MISS BROOK
This too is an extremely interesting pedigree
CLICK HERE While she is not sex balanced (and you will remember I said I had read on a thoroughbred site somewhere that a female offspring could be the balance of a pedigree that carried no sex balancing among the sire duplications).
BUT she is the result of mixing Credibility and City Smoke who are both bred on the Brother Fox/Pretty Short cross, one coming on the immediate sireline, the other on the immediate damline.
She is sex balanced to Waverly Supreme and has two daughter strains of Pretty Short to provide influence in the pedigree on the same lines as the two son strains of Brother Fox.

BOGIE LEIGH
CLICK HERE She has sex balancing to Chariot Supreme

BRUMBY LAD
CLICK HERE has sex balancing to Waverly Supreme and Temlee (and both trace back to Prairie Peg), as well he brings in the half brothers Acacia Park (through a daughter) and Brother Fox (through a son)

SLATER
CLICK HERE Has sex balancing to Chariot Supreme
but he also brings in that famous Laurdella Fun/Waverly Supreme nick, as well as a Rasmussen to Acacia Park and Brother Fox

BOOMEROO
CLICK HERE He's one who slipped through
as we all know there will be exceptions to every rule
his dam is very heavily outcrossed
but his sire is heavily in-bred
there was always a strong nick between Brother Fox and Grove Whisper
I remember reading a genetics book some years ago that was used as a text book at University in Queensland (Aust)
it made mention that if a complete outcross was to be undertaken in the breeding of canines, then one or both of the outcross parents should be heavily in-bred
maybe (and I emphasise MAYBE) this is what made Boomeroo a success
You will see he carries the import Grove Whisper as his damsire, and Boomeroo was a flop at stud (I admit he never got any real chance being a stayer)

SUN HERO
CLICK HERE Contains sex balancing to both Temlee and Waverly Supreme
and again brings in the half brothers Acacia Park (through a daughter) and Brother Fox (through a son)

I won't continue to go on and on
I think you get the idea

In Slippy Blue's case, he is not sex balanced
He carries Newdown heather through two MALES
He has a brother and sister through the middle of his pedigree which I would have thought was the influence in making him a quality galloper

I brought the pedigree of this dog, NZ star McCracken to the attention of Ken McLean and he was really amazed at his pedigree, the balancing but also the in-breeding to the half brothers

CLICK HERE
the position of Paris Match is all important in this pedigree

Mantra Lad is bred exactly the same way

CLICK HERE

DB

CLICK HERE
He is sex balanced to Temlee (through the male Little Blade and female Osti Lee in his sire Gun Law Osti, and the female Starfire Lady in his dam Sobbing Sal).
But he also carries a sex balance to Bandar Prince, and importantly as well, Little Blade and Pretty Short are bred on the same cross (by Temlee or a son of Temlee, out of litter sisters).
There is another sex balance to Benjamin John.

As we pointed out before, Gun Law Osti also carries in-breeding to a sire, top and bottom, 3x3 (to Temlee). Thus it would be then that Gun Law Osti demands a return of his damsire The Smoother in the pedigree of the broodbitch. In Brett Lee's case it is The Smoother's sire Bandar Prince (who is sex balanced as well).
I would have thought the fact Brett Lee carried half sisters Bonnie Secret and Academy Lass (both out of Secretly) almost demanded again that bitches with Pretty Short in their pedigree would be a natural for Gun Law Osti ... exactly how Brett Lee was bred.

would be the more 'suitable' of the half brothers.

Or along the same line of thinking, maybe

And here's one I looked at with our own girl too, me thinks you'd be pleased with it Dan ;-)

CLICK HERE

I was thinking Big Daddy Cool for a Brett Lee bitch and the 2 x 3 Sobbing Sal, yet a bit reluctant though there is strength in the damline. And am rather keen to double Brett Lee, as many others would im sure.

I haven't heard from you for such a long time.
Ken was fascinating.
I'm not too sure he would be into any breeder's conference.
I was lucky to be able to speak to him.
He constantly gets bombarded by people wanting to pick his brains.
I was fortunate to get to spend a few hours with him.

He said I would never look at a pedigree the same when I went home and he was so right.

DB

when you spoke to Ken - did you discuss any horse breeding

something like the potential for a Flying Spur / Encosta De Lago cross

or Redoute's Choice with a Umatilla or Hurrican Sky mare ???

He gave me the reasons behind his establishing Storm Cat at stud and what he looked for in any mare going to him when he first went to stud.
Ken would personally fly throughout the US to inspect every mare that had applied to be mated to Storm Cat.

He also discussed some of the matings he had done to achieve great success.

I was keen to discuss more general aspects of breeding and not specifics of which thoroughbred sireline would suit which damline etc etc.
Ken has a number of books out and all are fabulous reading.

I know he is extremely keen on duplicating similarly bred individuals in a pedigree in specific patterns i.e. (in the greyhound world) True Temptation and Flying Amy who are bred on exactly the same cross.
Obviously this is not the only way, but one he looks for.

Seriously thinking about this mating, does it tick all the right boxes for this theory David?

The other option I wan't for her is the most heavily inbred stud dog available inbred to I'm slippy, who would he be???

THANKS
