I don't understand how the atacs could fail like this. Doesn't the mechanism tighten when you pull up? I don't use the atacs, so I'm genuinely curious; this is how eggbeaters and their derivatives work, and they've never failed me unless my cleats were worn. Unless you twist out, this sort of design seems pretty much ideal for fixed.
