I'm curious what a genetic spider-like pattern is if its not actually the spider morph....do you mean a banded reduced pattern or like a woma?
As for morphs that might be good for you I'd think anything from the BEL complex, including fires, since you have that male super pastel, anything he's paired with will at least have pastel in it. Fireflys are always nice, but also a nice lemonblast or bumble bee would be a nice small step up thats not too 'high end', you would have much better chances of making killer bees and super blasts.Enchis are nice too. From a breeding stand point having a regular pastel male and then a super pastel male is kind of redundant so you could use a couple of morph females.
