Guys:
Just a note of caution since the season is just beginning.
I own both TD1s and TD2s. When I mounted my TD2s last year, I left the "short part" of my leash on my boot from my TD1 kit and used the new "long part" of my leash that was included with the TD2. The clicked together and looked the same. However, they are NOT secure. If you pull sharply, they will come apart. I assume there was some small design change since the parts don't appear damaged.
I found this out the hard way - on the hill. I released my bindings while sitting on the side of the hill so I could walk up to a missed turn. I dropped the board while walking, the leash separated and the board took off like a missile. I was holding my breath thinking it was going to kill someone. Thank God the slope was relatively clear and the board went harmlessly into the trees.
Check your leash! Give it a good yank to make sure it stays together.
