I have the Garneau Course. Only been out in them twice. Not hugely thrilled with the binding...it seems to work loose. I had to keep tightening during my warmup but they held for the race (4mi). It's also bites in to my shoes (and thus my toes) a bit because that particular binding is very thin wires. I can barely get my size 12 trail runners into the binding even fully-open. I like everything else about the shoes, I just wish for a less finicky binding, and I don't see the advantage of a supposedly "quick" binding in a racing shoe--you're not allowed to take them off anyhow. By the same token, I really wouldn't trust that particular binding in the backcountry.
