A question for old pin-heads... in the *freshiezone* Posted April 13, 2010 tip dive can be a few things. A skinny a ski in powder can stuff a tip easily, especially if you ski with a "one footed" technique. Too far forward a mount position is usually the cause of tip dive if the ski's width is appropriate for the snow depth and your technique is good. Wedges help with "rocker launch" by angling the front of the binding upward to compensate for boots that have developed a rockered shape with age. Wedges also reduce the "dead spot" in the boot's bellows resistance when the boot shape becomes rockerd and the boot gives no resistance until the heel is far off the binding heel plate. Wedges help give earlier bellows resistance, but would cause even more tip dive than you already have. If this ski is a hardpack ski, (less than 80mm underfoot) and you are skiing deep snow, it's likely that you are just stuffing a tip because the ski lacks floatation and the boot/binding combination is not active enough to counteract the rotational forces of the ski's resistance so you are launching over the handlebars. What ski are you talking about here? A good check for binding postion on a traditionally cambered tele ski is to lay the ski on the floor and put the boot in the binding. The ball of foot of the boot should be about in the middle of the distance between where the tip and tail points of the ski contact the ground. You can cheat forward 1cm for hardpack ski mounting and back 1-2cm for deep snow mounting.
