Might as well buy Flow
In my opinion this system does not make things any faster or convenient. I ride K2 bindings but not these clunkers. They are heavy and a pain in the ass to get in and out of. If you want a K2 binding that make things a little speedier for entry/exit I'd go with one of the Auto models. As with all "unconventional" strap systems, keep in mind if you break parts and expect to be able to fix them @ the mountain you might be s.o.l.
