My knowladge is basically from hearsay, but ill try to help. A super dwarf to noral would produce 50g super dwarfs or basically a snake the size of a dwarf. Super dwarf to dwarf is a combination of both 50%super dwarf 50% dwarf. (Size compairson is female dwarf:14 ft female super dwarf:10ft, so a 50/50female:12ft) hope this helps.
And as for the blizzard, id pm Monster Cages, I believe that's where your double het came from.
Hope I helped! Pm me and ill try to explain it better if my english failed
