^^^^ I love him!!!!!!!! I only hope mine age just as well. My female has a lot of blushing like that one, but the male doesn't. So, I think every single snake ages differently.
And remember, most mojave X mojave will produce a dirty BEL. Meaning, they aren't all pure white. Most have a purplish tint on their noggins. Which, I think look better.
What i would do is produce some baby mojo's and sell them to buy a different mojo. That way you aren't crossing your blood lines. Of course, some disagree that there is nothing wrong with inbreeding (that's how we have such gorgeous creatures). BUT a different snake, from a different clutch could offer so much more!!!
