Just one skiers opinion...
Last Fall I decided to stop using the this type of release system (Size 12 White Cuff/Carbon Plate/Single toe loop). I skied it with success and liked some aspects of it. 200lb, 34 mph skier with a size 12 binding. Set it up with the recommendation of instructors & experienced skiers including some on this thread. The binding / mechanism released many times when I would have expected to come out of a traditional (rubber) binding. Although, the block on the heel of the boot punched a hole (laceration) in my rear leg (shin) 4-5 times.
More importantly, I experienced what I would describe as an unexpected (early) release at the wake on different conditions. It is my opinion that the front of the boot (shell) compresses, plate lifts, or the ski flexes, and allows the toe of the boot to come out from underneath the metal loop / mechanism to release when it otherwise should not. I experienced two serious injuries in part because of it.
Too unpredictable and too many variables in this skiers opinion.
I have since skied traditional rubber bindings and had the same level of success skiing the course. I grew weary of the unexpected separations from the ski (early release) at the wake or the injuries to my rear leg from the front boot / shell upon separation.
Good Luck. Ski Well. Ski Safe.
