Replying to mad_trix system: durability + weight ?'s

First of all, I keep hearing how heavy these skis are, so not having a chance to ski on them, I decided to find actual numbers. I found a site that lists the weight and I was really suprised.

The 172's are 2704 grams with the system, and 1785 without. For comparison, the 172 Scratch FS is 1790, and the 171 1080's are 1680.

2704 - 1785 = binding weight of 919 grams!
This is lighter than Salomon's s912 Ti(990 grams).

Here is the page I got the weights from:

If you don't speek Japanese, you can translate it on altavista. Can anyone verify these numbers?

The only other thing keeping me from getting a pair of these is the question of the bindings holding up. The release lever *seems* pretty solid, but I'm worried it might wear out with lots of use. Anyone with experience on this?

Thanks
