" I would venture to say he had exceptional dogs? "
you would be correct about that sir, I worked him for 3 years for the gyp I know own, it took lot's of begging and crying and whining around to get her and IMO she is far above average and has proven to throw above average pups so far, lets hope the cross I made over her and my Abel dog doesn't change that or I probably won't ever get a chance at another one like her from him.
That's actually a very curious little method. Might do some playing with the theory myself. Sounds worth while giving a good solid test run with.
