The comment by BushwackerinPA
is partially accurate. The
real problem with this binding is that it is made for adv. intermediate
skiers and is designed for the toe to release directly upward in
a slow backwards fall. This saves the ACL from injury. For more
adv. skiers, especially in the bumps, this can cause a prerelease
problem when coming out of a trough. The heal of the binding is
designed to go backwards up to 1.5cm when the ski is compressed
into the trough of moguls. Coming out of the trough either the
binding heal needs to move forward quickly or the toe of the boot
moves backwards in which case the toe comes out of the binding.
( I've had a ski fly thru the air 10 to 20 feet while I tried to ski
a bump field on one ski )
That being said, I still love the ability to adjust the fore/aft boot
placement on the ski to find that perfect sweet spot.
On my 05/06 Dyna 8000's I have it two clicks (2/10") forward.
On my 04/05 Nordica 12SUV's I have it four clicks (4/10") forward.
On my 04/05 Dyna 8800's I have it six clicks (1.5cm) backward.
On my IBC 1300 Titaniums I'm attaching a 1/8" X 1/2" X 1.5" aluminum
metal piece to each wing. This will provide for longer contact with the
boot toe and help with the prerelease.
Regarding your boots. If they are over 4 years old, REPLACE THEM.
