Thanks for awesome info, most use is for gr3/4 with some rock and below 8000' alpine. Conditions range from days of -10 to March hero ice. Most approaches are a mile and then a scramble through talus for a good 200' or more. Did get a spiral fracture of my ankle on a stream approach in 2006 so rock hopping ability is another plus.
I do prefer a toe bail, and my M10's have a little life left.
