a_burgerAttacks seem nice but I will still stick with pivots, haven't had a pre release issue since I started riding them 5 years ago whereas my friends with attacks still seem to pop out sometimes when they shouldn't, and one friend had to get his re-adjusted a few times this year because they kept loosening.
I’ve had Look Pivots and SPX, STH and now the last 16 pairs of skis have been with Attacks all of them without issue. I HAVE had techs not set up the toe height properly on a couple pairs of Attacks and that’s the issue I’m sure with your buddy’s Attacks. Markers are the same in that they will pre-release if the toe height/AFD height is not set properly.
Techs should be testing toe height by trying to slide a spacer the approximate height of a business card or plastic gift card in between the boot sole toe and the Anti Friction Device(AFD) pad when the boot is locked into the binding.
You adjust the pad up until you can still move the spacer/business card under but there is some resistance. The step many techs seem to miss is once you have the toe height set, double check by pushing back on the top of the ski boot to try and “wheelie” the boot toe and check the toe height with the business card again. Many times there is still play in the toe still and the AFD pad has to be move up more. Once you can push back on the top of the boot and then slide the card under the toe with some resistance, you are set. Then try the other boot on the same binding as there is sometimes differences in wear etc between boots. Check the forward pressure as well as this too can cause a pre-release.
Follow these steps and you should have no issues of the Attacks which I highly recommend! Great light but tough bindings that you can always find on a deal.
