La Troienne's tail female descendancy has produced many excellent broodmares and several popular sires. Ergo multiples of her are pretty common in back pedigree of the contemporary TB population. Those multiples almost certainly aren't hurting Speightstown's progeny but many, maybe most, of his successful sons & daus. have much closer inbreeding/linebreeding that is probably more significant in terms of that success.

Given the gist of the original post there's a certain irony in the fact that Speightstown's nearest competition on the leading sire list is Kitten's Joy. His chief earner is Big Blue Kitten who has three crosses of Buckpasser but got none of his X chromosome.

Hi Pan - I am sure there are closer duplications than La Troienne in many of Speightstown's stakes winning progeny, but I would not discount LaT's significance.

Distorted Humor does not have a single Graded Stakes Winner that is not out of a mare carrying LaT. John Prather and Les Brinsfield "profiled" Distorted Humor when he went to stud and advised that they breed to as many mares carrying LaT as possible.

Interesting point about Kitten's Joy - he is a tremendous sire but his yearlings are generally unimpressive individuals. In my experience they have a big growth spurt between the yearling sales and May of their 2 year old year.
A difference of opinion is what makes horse racing and missionaries.

not quite true Da Hossmanb but close...Then the unthinkable happened. Les Brinsfield sent an email in early 2010. It read: “End of streak. It took a horse from the 8th crop of Distorted Humor to be first graded SW in northern hemisphere from a mare NOT carrying La Troienne when Radharcnafarraige won a Gr3 in UK.”

Since somebody cried to a moderator like a llittle girl to get the Buckpasser in th X thread locked up, how about we cease such comment.
