Bought these bindings back in April to go w/ my new K2 Format. I just used my new set up this past weekend down at Heavenly at Tahoe. After a day of riding I've come to the conclusion that these bindings are awesome. As an intermediate rider I progressed so much in one afternoon of riding. I struggled w/ making crisp turns on my last setup (Sims Absolute 159 wide/Burton freestyles), but the K2 Indys were very responsive. I was able to easily cut through moguls at high speeds. These bindings are hella comfortable, and they are lightweight. On my last setup I felt like I had to fight the board when I wanted to turn. These bindings made turning easy. I really like how easy it is to make adjustments to these bindings. However, make sure you check all the strap buckles every few runs to make sure they are locked into place. Other than that, they are flawless. I feel confident that I will continue to dramatically improve as a rider with these bindings.
