rolling ski bags

Pugski asked me how often I used a ski a bag, and the answer was at least once a week. My normal routine is to pack two or three pairs of skis in a Level Nine soft-sided bag, lug it up the basement stairs, throw it in the car, and head to the local hill. There it gets put outside on a wood deck...

Thinking of selling my skitube duals (a little unwieldy to travel with) and going soft 2 ski roller bags? I've read some good stuff about the thule bag, but also the sierra bags and the dakine boundary bag. Any reviews or anectodal evidence one way or another??
