Best meaning the most likely to produce field trial winners
A half decade into the last quarter century it could validly be stated that A Rambling Rebel (although deceased before he was so recognized) was the best sire of field trial pointers. Most of his sons and daughters won (59%). He had a Prepotency Index (PI) of 1.43. Recognized earlier in his career than A Rambling Rebel, the next star on the horizon was Evolution that had a PI of 1.20. A contemporary was Flush's Country Squire that had a PI of 1.10; of his get, 47% won. At the start of the last decade of the century Miller's Happy Choice with a PI of 1.08 and a Winability of 197 and Blackbelt with a PI of 1.06, a Winability of 218 and 46% of get winning led the list of studs in the 1990 Almanac. Understatement was putting more run into his pups that any other sire tracked (with the exception of Mortlach) to this date. Also an amazing 46% of his get was winning. Moving well into the 90's the next stars on the horizon were Barshoe Brute and Double Rebel Jack. Respectively they had PI's of 1.20 and .91 and Winabilities of 223 and 207. As we head into the new millennium the evidence is conclusive that the best sire is Black Crude (53% of get winning) with PI of 1.37, a Winability of 296, and a Major Circuit Index of 2643. The second best, Go Boy's Shadow (41% of get winning) stats are 1.11 PI, 197 Winability and an MCI of 2378. Both are deceased.
It is of interest that Barshoe Brute, Double Rebel Jack, Black Crude, and Go Boy's Shadow are descendents of A Rambling Rebel. Blackbelt, Understatement, Barshoe Brute and Double Rebel Jack are descendents of Flush's Country Squire.
One of the unfortunate phenomena in selecting studs based on likelihood of getting winners has been that by the time the dog attained a high PI he was dead. With that in mind the answer is often one of the sons of the great producer. An oft asked question is what are the best bloodlines or what cross should be made to get the best dogs? The answer changes with time. With the expression best meaning the most likely to produce field trial winners the answer would be:
Breed a son or daughter of A Rambling Rebel to a son or daughter of Flush's Country Squire or Evolution.
Breed a son or daughter of Miller's Happy Choice to a son or daughter of Blackbelt
Breed a son or daughter of Barshoe Brute to a son or daughter of Double Rebel Jack
breed a son or daughter of Black Crude to a son
or daughter of Go Boy's Shadow
