First of all, tall tees will probably help the issue but I doubt they will solve it. I would also suggest getting the full tilt booters. If at all possible buy line afterbangs and forward mount them with PX18s. It does not matter how much you weigh. If you forward mount them you'll be able to just sit back and tail gun, which will allow you to charge regardless of the terrain.
You might also not be afterbanging long enough after landing, which could result in you falling due to the excess of that annoying powder stuff. Having a good solid afterbang will get you back on those tails and I guarantee you that you won't be falling over as long as you're sitting back that far. It sucks that you have to ski pow, it really gets in the way when you're trying to get speed for booters and such, and landing is just straight up a bitch. I'd highly suggest getting out to a nice groomed resort with lots of rails, it will make your life MUCH more enjoyable. I used to ski pow but then I started skiing park and I never went back.
