Fischer and Rossignol went in on a joint binding project that resulted in the creation of the IFP platform. New skis from both Fischer and Rossignol that have the IFP plate now require an IFP compatible NNN binding. In addition to this, Fischer took out it's extra top lamination this year which allowed screws to be used on Fischer skis. So, it's easiest to remember that if you have an IFP plate, don't drill, get an IFP compatible binding and also make sure you have an NNN compatible boot.
The Turnamic World Cup addition has an extra little locking mechanism on top. Fischer Turnamic bindings open by swiveling the lever on top sideways.
From Fischer- New TURNAMIC® classic binding developed for World Cup athletes allows them to precisely position the binding, quickly and without tools. Safe Lock feature prevents unintentional opening of the binding during race action. FLOWFLEX® technology allows binding to flex with the ski for optimal power transfer.
