As a result of the Ice9 crampon recall I had Montrail send Sabretooth Crampons as the replacement. I had to purchase the ABS kit myself. With my size 14 boots, I was very concerned about too much flex causing problems with the Sabretooth staying securely fastened to the boot. I did not have to worry after all. I made it to the summit of Mt Adam's a few weeks ago without a single crampon problem. I had no real issues with balling. And this was after several inches of fresh snow the night before summiting. Something I cannot say about the Ice9's. I had problems on Baker keeping them on my boots as well as snow balling up. One side note, to use the Sabretooth crampon on the Ice9 boot I did have to grind away some of the toe of the boot to widen the bail groove and make the toe bail fit snuggly. I do not think this will be necessary for smaller size boots.
Happy climbing!
