A known issue with Dynafit FT12 binding is the lack of support under the toe wings, due to the narrow baseplate (our theory is that style trumped function, but who knows…). At worst, this lack of support could lead to excessive stress on the steel binding base and subsequent breakage. At best, urban legend holds that having a toe unit base as narrow as the FT somehow makes your skis perform noticeably worse or even contributes to the possibility of binding pull-out. While we’re skeptical of the latter (except in the case of racing World Cup slalom on Dynafits), we are believers regarding concerns about FT binding durability. Hence, if you’re of average size or larger and ski hard with big boots and skis, we recommend this mod for the Dynafit FT12 backcountry skiing binding. Conversely, if you’re a mellow skier (like me), you probably don’t need this mod so don’t panic. (Click images to enlarge.)
I see only two minor downsides to the Power Plate. One, it adds 8 grams per binding. Two, and more importantly, the Power Plate will obviously exacerbate the build up of ice under the toe wings due to to the plate forming a rim to the rear of the binding. This type of ice buildup is in our opinion one of the reasons people sometimes experience what they think is an pre-release problem inherent to the Dynafit binding design, when in reality they have a wad of ice keeping the binding from totally closing on their boot toe. Thus, if you choose to install the Power Plate, simply be more vigilant about checking for ice under the toe wings and cleaning it out if necessary.
