It's not a noob question because nobody really knows the answers for sure - or if they do they aren't saying.
Doesn't seem to be any visibly different superform reported, nobody has a definate homozygous spider that only produces spider offspring ( though there is now an intresting candidate for once ) but there are also no signs of dead in egg babies or slugs to account for the 25% chance per egg of a homozygous spider when breeding two spiders together.
Kevin at NERD has said it isn't a lethal combo, and the amount of wobble passed on seems random, so I can't think of any reason not to breed spider to spider other than the fact that most people would rather make more two gene combo's than just twice the amount of spiders in a spider to normal pairing.
Personally I'd love to have an ultrasound and 20 breeding spider pairs just to try and find out once and for all what the heck is going on.
