You nailed it in a way I haven't been able to describe...once dialed in, my NXT FRXs (Flow's stiffest, I think) just make the board feel like it's a part of me. I got Flow's The One boots, too, figuring they'd be a good fit with the bindings. They are. Mounted to my NS Titan, the response is incredible. I can't believe people could have a bitch with these bindings unless they just don't know how to get them adjusted properly (or didn't bother to take the time to do so).
Gotta say it again, though; cheap Flows are...cheap. Don't waste your money. But anything in the NXT line is sick.
BTW, sweet set up you got there!
