I paid $125 each for each of my big three 2000+ proven normal females.

Would I pay $160 for a unsexed larger normal? No way.

I'd wait and get a actual female normal with size or go with your Mojo. If this normal turns out to be a male that you have no breeding plans for then that's your $160+ pet (which isn't a bad thing: I have snakes that I have no intentions of breeding) but you could have used that $160 for something you really wanted.
