Only you can really answer that. If you like them enough, go for it. Or wait until after the show. Or buy the male now if you really like it and pick up the 2nd one at the show. And of course this assuming you trust this guy and you believe the genes of the animal are what they really are.

For me, I didn't want a 14' snake so I got a SD/D but I had to find a reliable source as people can claim whatever % and its all based on the trust of the breeder. I ended up getting my boy from Vital Exotics.
