Familiarity: I've put it through the wringer
I've used these almost a year now with my lighter, narrower ski mountaineering setup. Rotating the heel takes some getting used to after starting with Radicals, but I trust this heel more. Have had one or two "auto-rotate" incidents when using risers, but I try to avoid using them.
Review loses a star because the toes are not exactly the same as you get with Speed Radicals. These are the same (newer 4-screw) hold pattern, but they lack the "power towers". I'm not sure this makes a difference.
