Quick heads up about making them super soft (still your call though):
I wouldn't make them really soft on your first pair you make, it takes some time and a couple pairs to really get the making process down and the softer it is the easier your ski is going to break / slowly fall apart.
My dad is pretty good at making skis at this point and he made me a super soft pair, and I mean soft as in I could butter the fuck out of these things, and they got destroyed pretty quickly (take into account I jump on rocks and do stupid shit on my skis a lot).
If they're gonna be primarily pow skis then it won't be as big of a problem, just a heads up.
Good luck and let us know how they come out!
