it's only a wind up comment mate for mchull, but he's too experienced to bite, coursing dogs are the best at what they do, but a good whippets prey drive is as high as they come.
totally agree with you, quality is a big factor as well wether it's nylon or poly, I got something called crossbraid nylon off netrigger on here and I think they are better than anything.
I couldn't get on with it, I think good nylon beats it in every way, not just pursenets, for longnets nothing beats 4z nylon for tangling rabbits, I mean proper longnets for night netting.
neighbour had one when we were kids in the 70s, first cross black dog, he took everything available, rabbits, hare, fox, and feather. he was racy built with labrador head, my only concern would be a lot of them being to heavily built, good luck.
it's certainly opened my eyes at what they can do, biggest surprise is how good a nose they have, beddywhippets have a great nose, but this whippet is on a par with them.
I don't know if he still breeds whippets, I know glover has a half brother to my bitch and a dog that's bred same as mine, can't fault the breeding but that's down to the chap at pennymeadow
