Okay dont wanna produce fire spider pastel crosses because they just look killerbee ish (which I dont agree with anyway look at killerbees and firebees as adults BIG DIFFERENCE) Ne Who check out the Nuclear bee.....http://www.worldofballpythons.com/morphs/nuclear-bee/
The bottom of the line is what fire does to anything with pastel in it may look comparable to a lower end super pastel at birth, look at the two as adults. There is a good reason Super pastels are worth half of what a fire fly is
