User Review: MSR Men's Lightning Ascent

I bought them last year '07, used them 6 times. Snow was always hard. They slid on ice going downhill. This year first time out lots of fresh snow sinking 16-24 inches, thought I might be spending the night.

I am new to this 6' 3" and with gear 250 lbs. Sales person said they would do the trick, and MSR also rated them for 225+ lbs.

I am now looking for a new pair. Anyone know of a brand and style that will do the job?
