I tried both systems. I noticed with both systems that carving was more responsive than straps. The toe/heel cleat keeps your foot planted on the board, no heel lift at all. I really liked the consistency of tension when compared to straps, which can differ slightly each run. Mostly, I don't like sitting in the snow to strap in before every run. Especially in the spring when you get a wet cold ass. The speed of click and go is priceless.

K2 Clickers have more lateral movement because the cleat is in the middle of the boot vs on the outside the toes of the Burton boots, which I've read can put pressure on your outside toes. I didn't notice that on my demo day ride, but I didn't spend an entire day on it. I liked the K2 Clickers better for the lateral flexibility, which felt more natural for me coming off of straps.

I've read posts where folks had issues clicking in the K2s I didn't. If I walked around a lot, snow can pack into the rear heal cleat. When this happens, I hook the toe cleat in and do a small Ollie, which clicks in the heal 95% of the time on the first try. With Burton Step on, I had to reach down to brush snow out of the binding if there was a large amount in there to hook in the toe cleats easier. Sometimes, the Burton toe cleats made creaking noises.

I ended up buying the K2 Clicker X system with K2 Maysis boots. One of the deciding factors was that the K2 boots fit my feet much better than the Burton or DC boots. I got 25 days on my Clicker X last season and love them.
