Here's what NERD has to say about Mojaves: http://www.newenglandreptile.com/ner...ll-python.html

"Mojave ball pythons are highly variable - some are light, some are dark, many have brilliant gold-and-white pigmentation on a dark background, while others possess extreme blushing & greenish undertones. Regardless of coloration, Mojaves all share reduced patterns with "teardrop" or "keyhole" lateral blotches."

Really it comes down to what YOU like, though... I just purchased a Mojave from JKobylka, and picked based on what looked pretty to me.
