I rode factory bindings last year. They were great. Maybe a bit too aggressive for me as it was my first year riding. Thinking a softer binding might be better for my skill level.
I just don't want to get something that feel sloppy on a stiffer board like the Ripsaw.
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.
