As everyone else said, buy more females and fewer males. Possibly 0 males your first year purchasing.

With genes like pinstripe and spider, which have no (known) super form, it doesn't make a lot of sense to have very many copies of it. That's relative, of course; if you have a huge collection you'll need more than 1 copy. But since you listed only 5 snakes, I would not choose 2 that both carry pinstripe.

Buy what you like, and that means not only the genes you like, but the particular look you like. People will say "buy quality", and I agree with that, but it has to be what you consider quality. Reduced patterns are really popular, but personally I really like a busy pattern, especially on certain morphs.
