To answer your question about aggressiveness. I charge when it's a pow day so if you're in my way I will let you know. I go fast and hard and I'm usually done by Noon as I've gotten my fill, can't speak for others.
I'm pretty much the same. I'm as aggressive as the dude pushing behind me. If they get all crazy, it gets ugly. Rarely happens, only once this season and it was actually a lifty being a total bitch. Unfortunate for her the mountain safety, patroller and lift manager all are friends of mine..... She had a bad day.
Everyone gets powder fever. Powder good... My group of 8-12 are always first gondola. We get lots of fresh lines and we are all pretty fast in all terrain. Such a good time charging and there are never really friends on pow days, people stay outta the way cause we are coming...
