i got next years nxt fx's right now. i like them for just cruising around the resort but in the bc or deep pow i hate them, too hard to get in and out of. i also broke a buckle on a pair of fx a had before, then striped the threaded insert for the heal piece on my new ones. now i will say the first pair i had was a proto type lent to me, so they werent as well put together as the manufactured ones and i also broke it on my split board in ski mode, the inside buckles bashed together a few times and one snaped off. the heal peice problem was probably me over tightening, but i still wasnt impressed. as far as getting in and out quicker then straps....i call bullshit on that, i havent found them any faster. the major benifit i like with flows is there comfy, no presure points, and respond nice they have a lot of adjustabelity.
something else that i like is when i broke the buckle on one i was in the bc, because of the suport in the strap i was able to ride out no problem. if i had the buckle break on strap in bindings it would have been alot harder to ride out.
