If I were you and I was thinking of eventually breeding, my first boa would be a female. They need to be older and bigger than the males to have a successful breeding. I generally like my males to be at least a year younger and half the size of my females.

That said, I'd go with a DH or even a TH female, wait a year or two, and then get a snow or DH Snow male to pair with her. If you get a male now and then a female next year, you'll be playing catch up trying to get the female bigger than the male to breed successfully.

Summit LINE Pastel is a pastel trait "fine-tuned" by Summit Reptiles. It's their "line" of pastels. Pastel is coined a polygenic trait. It's not recessive or dominant, but selectively bred to look the way they wanted them to look. Very nice line to have in any collection. Other Pastel lines are Ronne, Aby, Peachy, EBV, etc.

Pastels will take any morph to a bigger and better level.

Hope this helps.
