Just ordered a real tick ski

It made the wallet a bit to thin so I decided to save on rear binding.
A friend will cut out a rear binding plate for me and I have the rubber (he needs to do this before I get the ski)
So far so great.
However I just realized that the hole pattern has changed 2014.

Making your own plate will allow you to get your ankles closer together - this greatly enhances stability on the ski and eases the "new trick" learning curve.
At the moment the new stuff budget is low.
Also few plates available in Sweden....
The plate is ready to be cut out using my buddys watercutting NC machine.
Just a small adjustment in the CAD data.
Cutting time is fast.
Tanks for advice to mount a bit apart!
