I have the Rossi Axial 2s... same binding. They great bindings. They have the same elastic travel as the older axial line. Forward pressure is adjusted with a tab (like the axium bindings) and a yellow window indicator.
They hold on great and release when they need to. They also feel a little more responsive than the older p-series... but then again, I've only skied with them twice this season so far. No complaints so far though.
i ride both old and new, p12s on my PEs and px12s on my pollards, i like them equally. my px12s are brand new so they feel nicer but they're both just dope, you really can't go wrong...
