No one has a spider that always throws spiders (at least not the "big boys"). I asked Kevin about this specifically back in October when I was up there visiting. He is the originator of the spider and he does not believe that there is such a thing as a super form of the spider, nor does he believe that super spider is lethal. He just believes it simply doesn't exist, nor will it ever exist. We would have seen it by now.
Brian believes he has a homozygous (super) pinstripe that has thrown all pins over many clutches. It looks no different than other pinstripes.
