but i think the first example is more realistic today. i do know that a BEL pastel exist today (i think ralph davis produced it, but im not 100% sure). so i think in near future someone will hit on the BEL super pastel. i bet someone is working on it right now...
i hate all those pre made calcs, this one can't get screwed up..... http://www.geneticswizard.com/

spider gene can only be het to our knowledge, so its impossible to have a 100% chance for spider babies. both parents having the spider gene would give you 25% normal, 50% spider, 25% homozygous spider(which to date does not exists and hasn't been proven and that why its thought to be lethal)

the pair you listed should yield 50% killer butter spiders and 50% killer butters
