Nnngghh, don't doom me any more than I already am, Bogertophis! An employee at my local reptile store did warn me that with ball pythons, exceeding 2 is the point of no return and then you jump straight to 10, which was why I put on the brakes after getting Iggy and Rae, lol. But she didn't give me any preparation for what to do when expanding to a new species! I started out just looking at the BCI morphs with strong reds in them -- I actually just emailed Vin Russo to inquire about current/upcoming availability for some of his Hypo Bloods -- but already my treacherous self is thinking about what another color boa that could complement that blood red! [facepalm]
He has a line of pastels that might tickle your fancy You can get the red without it drowning out the pattern and contrast. You can also throw the pastel into morphs as well, something to look into.
