Some things are on point, some I agree, some is irrefutable. I agree, about the difference in bolio dogs and hollingsworth, it's why I made the breeding with hollingsworth bull. And yes. My dogs are mostly buck. .. Like Mr. Machobuck, but Machobear has more hollingsworth mixed in. Yes Machobuck was Buck in a Mayday body. .. Be it hollingsworth or yellow. And yes. . I believe redboy dogs have been over bred, but I've seen dogs off Hatfield's Taz consistently produce make you cry game dogs with a plethora of bitches. Who is a gamer line as a whole, tough to beat hollingsworth, I even think gamer than yellow or buck line slightly. . My absolute favorite breeding of all time was the Mayday - Blondie breeding. It was a masterpiece. A grand champion son of Grandchampion and best producing rbj dog of all time, bred to one of the best producing bitches of all time straight from old man Hollingsworth's yard. Bottom was out of a grand champion who who beat a grand champion bolio tombstone dog, to one of the best producing rbj gyps out of yellow from litters that were consistent. Mayday, choice, dragonlady, Madonna on top, Gr. Ch. Yellowbuck and ch. Piggy on bottom. I've tried to breed around that, adding tonka bear , deadlift, your stuff.. . Always keeping around the same %. 50-50..next few years will tell the tale.
