Starting to breed Ball Pythons, what morphs should I start with?

Thanks everyone for your input, I really like the idea of a pair of mojaves and enchi X leopard.

I haven't bred yet but I'm at the same point as you. I'm not going to breed for the money (money will just be used to supplement racks, feeders, etc) but at the same time you don't want to be breeding a bunch of normals or undesireable snakes. For recessives I think visual pairs or male visual to female het are good ideas (granted they just cost more than the common co-doms), but buying double hets I just don't like. Sure you can get a het pied breeding pair at a show for 100 bucks EASY, but then you'll end up with 25% pied (yay!) and then 75% will be normals that are 66% poss het pied. I'm sure you can rehome the normals, but it's harder and they're just not worth much. From what I've seen they sell for a little more than normals but they just don't move fast. So you could be stuck with a bunch of normals that might or might not be het for pied that you still have to feed/house/etc.

I personally have a bigger budget to work with so I'm going to be going for banana pieds (which I could go into more if you wanted), but with a smaller budget I'd go for a multi gene male and single gene or normal females. For me I have access to cheap feeders so multiple snakes (to a certain point) are a no brainer. Ideally you would find a 3 or 4 gene male, but I can find nice double gene males for like 200 or less on kingsnake. Then just get the cheapest (as in good quality, not loading up on petsmart females) females for however many you can support. So with that pairing you can make clutches that are 25% normal, 50% 1 gene, and 25% 2 gene. You won't make good money on those clutches really, but you'll be creating animals with more value so it'll be easier to find homes for the ones you don't want to keep. Plus it'll be exciting with the multiple gene ones to see what you get from each clutch, like bumblebees, lemon blasts, etc.
