^thats a completely diff. binding, not slightly diff. and no, get whatevers cheaper. all look rossi turntable binders are identical. brakes can be bent, risers and screws can be removed/shortened.
and about lifters....
lifters allow you to put more leverage onto the ski, by increasing the distance btween the snow and your boot. however, it also makes them less stable. on twintips, its very noticable, but the effects are not neccesarly good. i skied 4 yrs on non lifted p12s, and last season on lifted ones. i noticed no real diff on rails, but on jumps it was very evident.
