I just rode my proto with the genesis bindings on them... Match made in heaven. My bosses will never go back on the proto now. Although I don't have the privilege of riding your terrain, I like to do tree runs (shitty mi ones lol) and some freestyle.
It's nice and playful when you need it, but responsive when you drive into the highback thanks to the hammock. Very comfortable and light bindings.
I do find myself missing canted footbeds though.
Interesting. Just demo'ed the Genesis on the Cobra for a couple of days and I am going back to the 390 Bosses - think they are both more responsive when I need and more playful when I want.
