Paulo what you says has some merit but at least the new starter  
has got a free pair to start with and kind of the breeder to give them free   also what you say about the bushys is partly true there where many fanciers from other areas who done really well with them  
the birds you bought at Johns sale are the goods i have been friends with john for over 30years and if he was not terminally ill they would never be sold  rember one thing peds mean nothing to john and he was a very hard task master no matter what he paid for them if they did not win or breed birds to score very quickly there was only one place they went in the garden  winners to winners  they breed winners best of luck with them
