I'm not toooooo dumb, though I few falls in the trees may have made their mark
Anyways-- I've skied anywhere from 2cm infront to 3cm behind midsole on a normal ski, but what goldsbar has are not "normal" skis. They are Fischer SC race skis with a race binding. Now if he wasn't going to race being a tiny bit behind or infront wouldn't be a big deal. If he is going to race then they should be right on the line. With race skis you really have much less give around mounting position than normal skis
Sorry, but this nonsense. Please spend some time educating yourself here on Epic regarding binding mount position.
