From my understanding from a top Atomic Race Rep. that I spoke to many times when my boys were sponsored by Atomic, all the Atomic athletes still use the Atomic Race 10.18 and no one is set higher then 16 on the World ccup.
It is the exact same binidng you and I can own (in fact I have about 6 pair in the garage right now!)
From my experience (and i ski on 3 pair of FF17+) they have been absolutely bullet proof. BSL of 313mm. I am 6'0 190 ski on a Din of 10 and never release. Pre or otherwise. I trained GS & slalom all season and did some freeskiing SG/DH training.
A pre-release problem is either binding is set-up wrong, (Not the release tension but the forward pressure) or sorry to say it is the pilot.
If you lose the pressure on your outside ski in the wrong part of the turn racing, ain't no binding on earth is going to keep the ski on your foot!
I would suggest the OP and everone else with their screwdriver out read this from Vermont Safety Research before they crank their bindings into the stratosphere! If you are still coming out when you shouldn't by all means crank 'em up or take a lesson!http://www.vermontskisafety.com/vsrfaq8.php
But I found the underlined portion below extrememly interesting and in direct conflict with popular opinion as stated above!
And I quote:"The RATCHET Effect
-- A good example of the rush to readjust is what we call the Ratchet Effect on the release adjustment screw of competition bindings. Race bindings are tightened for a variety of reasons (most of them wrong), but are rarely loosened.All research efforts to date show that the magnitude of the load a skier applies to a modern binding toe piece decreases with speed (even during competition) and yet all problems of retention (inadvertent release) are blamed on the binding setting.
