Dog breeding question - Barlow, BigO, Parker, Texashogdogs, etc

I consider a cross a good one when I don't have go through too many to find some good ones. You need some help in my opinion, to breed hunting dogs. A man can't start more than a couple of pups at a time without having problems. I know some folks that are good dogmen and good hunters that like the same type dogs that I do and will flat hunt the hair off one. I give them all they will take. I have made a couple of mistakes over the years in breeding these dogs and these same people have saved my rear end from loosing it all. I started with dogs from a great cross, so its been hard to improve them and a struggle to mantain them, but they are capable of producing some great dogs. They also produce some junk and more so so dogs than I would like and have found it impossible to produce the percentages Of what I call good dogs that other people claim. It doesn't bother me to cull a whole litter, after trying them, but when you see me unsnap one, it's a good one.
