I believe Mr Colvin has speed buggy too. He is raising some nice pups off Snowman and the Cat squirrel dogs. Ran at his place a couple of weeks ago and saw some nice looking pups running around.
Where are you located? We have Top Flite Buck in South Alabama he is off Casper and a Rick's Zippo gyp then Jack Floyd in Northwest Florida has Ch Floyd's Red back from David Hellums he is off Casper. Floyd kennels also has several other nice dogs to breed too as well. Jeremy Cotton in Northwest FL I believe still has Ch Cottons Moneyman off Casper and an Almond Woodstock gyp and Mr. Colvin in North La has Cottons Rainman which is money mans brother. Jamie Sauls in NW FL has Gunstock Billy he has one heck of a mouth! Then there is RDs Jesse James off Casper he is in NE FL or South Georgia. I'm sure there are several more around just the ones I've heard of
