I did enjoy the way the bindings worked, not so much because it was faster, but I just found it super easy to lock in and get out of.
super easy in/out means faster, that is their design principle, faster and easier and simpler and comfortable.
It sounds like you like that, what did you not like that you want to switch to a similar style.
I rock the 2010 model.
What about the Ride Contraband's??? similar but not "as" fast, but I hear a responsive binding.
just a thought
