On such an aggressive board, softer bindings will actually hinder you as you will struggle getting the board to react...
If you dont wanna go too stiff, then maybe Atlas, Ride Capo or Burton Genesis. Other good options could be Ride Hefe, Now Drive, etc.
Check out the colorways and see which one looks best.
Ride El Hefe..... Ugh. Worst binding ever. I had them for a whopping 3 weeks last year.
Very poor construction.
