gnzdbwczwrote a review of Gnu Park Snowboard Binding - Men's on February 10, 2012
Writing and inital review on these, I don't think theres enough reviews out on the Fastec Gnu bindings yet. I will post an update after riding them a few times.
I didnt actually purchase the "Park" bindings, but the "Choice" bindings - which have slight upgrades.
I'm used to Burton (Mission/P1/Cartel) bindings, I like the toe cap strap and the security of a fixed hinge highback. These Gnu bindings are a new direction for me.
After mounting on my board - I found it pretty easy to make adjustments, rotate my highbacks, etc.
The forward lean on the Choice is a tool-less turnbuckle threaded screw on the cable which simply makes the cable tighter.
In and out on these is a piece of cake. Release the lever, flip the highback down and the ankle strap pops loose automatically so you can pull your boot out.
I recommend watching the setup videos on Gnu.com.
Pros: very lightweight, easy in/out, nice adjustability
Cons: alot of release levers have me questioning long-term durability.
** UPDATE 3/5/12: - Used these for a solid week in Utah - very nice. No issues at all. Once you get the straps dialed in to fit your boot tight enough with no pressure points and no heel lift they are rock solid and ready to go.
