yeah well you don't see people crossing like cocker spaniel and Rottweilers do you? Just kidding do what you do but just for the record I can't possibly be anymore against that Just saying but like I said before it'd be pretty boring world if everybody liked green lolI know all the guys on here will be mad at me.. but I think its a good idea. If you want something specific than go ahead and breed it. If it works then more power to you.
I cross breed different strains of games all the time and I have good results despite discouragment from "pure' bred enthusiasts.
