How are Gnus faster than Flow? Even if you have to adjust the strap a smidge, with Gnu you have to clip that stupid ankle strap down. And the ones I rode the toe strap did not stay in place. They asjusted them for me. They felt like 3 year old rides with highbacks that were too canted. One of the worst bindings I've been in.
If you were trying to get a two strap feel even with the hybrid strap you were doing it wrong. It's not a traditional 2 strap and the toe strap is not a traditional cap. It grabs the front of the boot and pushes back. If you just dont like the overall feel that's fine, but the tech is solid and much more thought out than Fastec.
Go ahead, drink that kool-aid.
