I think I'm just going to copy your list!!!
I'm pretty new to ball pythons, so I am constantly finding morphs that make me say, "OOOOHHH! What's THAT?!" and as I looked up the Axanthic Firefly and the Lightning Pied I now have two more "must haves". I also really like the Banana GHI and the Banana Ktulu... and I can't wait to see what a Banana Sunset actually looks like. The nice part is that my wife really likes the Axanthics and GHIs, so trying to convince her at some point down the road that I need to spend $5k+ on a GHI may be easier than if she didn't like them.
Other snakes that are high on my list are
- Axanthic Champagne
- Mystic Potions / Super Phantoms
- Lesser BELs
- Super Black Pastel (and Panda Pied)
I'm sure there are a hundred more that I'm forgetting right now, but these are the ones that I am currently in love with.
On the flip side, the one gene that I have no desire to ever have in my collection is the Spider gene. I know that it can do some really cool things to a lot of different morphs, but my buddy has a Bumble Bee that is SUPER derp... just watching it move around upside down, and the STRANGE things it does inside it's enclosure have turned me off from the gene. It's 100% a personal choice, and I totally understand why people like the snakes appearance, but I don't like it.
