I would start with either a pastel het axanthic or a spider het axanthic female, and the shop for the other gene in a male a year or two later.
If you start with a bumblebee and an axanthic, you'll have to breed them together to get the spider and the pastel het axanthic... and you'll have to hope you produce them in a opposite gendered siblings, so you can breed them together a few years.
Of course, if you start out with a bumblebee and an axnathic you DO have some neat morphs show people, right out the door. And then maybe you'll get very lucky and hit the bumble het axanthic in your first pairing (which you can then breed to a plain old het axanthic. Or even to another pastel het axanthic, which would let you try for the super zebra.)
I do see the appeal either way, if you're starting your first big project.
