There genetically must be some sort of Super for every morph- visual, or not. Whether it's worth a hoot, or not is up for debate. I personally think it could be worth something. What if I really wanted Kingpins? I could pair a Lesser (or it's super- BEL) to a SuperPin and increase my odds of getting Kingpins, or shall I say less chance of normals. It could certainly come in handy for a Nuclear Pin if one desired to breed for those. Give me a super spider for nuclear spiders at a few grand a pop and I'll take it.
To say that Pins do not have a super form when other morphs have a super form is kinda silly. Just because it is not visual does not mean it does not exist. It would take years to prove out and even then someone will just say you hit the odds real good and you could not prove them wrong without genetic testing because it would not be visual.
Proving out a non-visual super pin seems kinda cumbersome to me- especially when we're talking about a $200 morph. I'll just play the odds with more pins..... kinda what I'm doing with Spider morphs for my Nuclear spider project.
