Just made the first purchase of my for fun BP breeding project. 09 female lesser. Waiting for weather to warm up to ship. This will also be my first snake that is not a normal.
There's thousands of options out there you can play with the genetic calculator on worldofballpythons.com to get ideas. I love ghi lessers and anything lesser/enchi is really nice also.
If you want to go the bel route I'd suggest a Mojave, the mojave/lesser combo usually produces the cleanest all white snake. Also lesser/lesser bels come out with bug eyes alot of the time.
