^^^^ This. But seriously, you have spectacularly mismatched skis and boots for what you say you like to ski and your size. I owned the Bandit X's, great ski for its time, still a wonder in bumps, but no way I'd want it in heavy backside conditions. Trees, maybe, if there were no new snow and lotsa bumps. And 85 flex boots, wow.
OK, here's the program. I'd guess from the amount you've skied, per year, or every other year, that, uh, you DO need lessons. Badly, if you plan to go buy modern gear. Skis, for instance, have evolved so much since the Bandit X's that if you just step into a new pair you'll probably be searching for your ACL's for months. And as a mostly self-taught guy, skiing since age 3, I can testify that my style was bad mechanics and wonderful balance to compensate for all the other bad mechanics. I could ski most things, just not safely or efficiently. Lessons and/or racing are wonderful things, honestly. So:
1) Go buy some decent boots first. Something with a flex of about 110 minimum. Get them at a slopeside shop so you can have a good fitter and get them tweaked. The places you ski will have several reliable shops. Or do a search here for recs.
2) Rent some modern skis in the 95-110 mm range.
3) Take a lesson on them.
4) Repeat (2) and (3).
5) Then look for deals on new skis after Christmas, or ideally, President's Day.
