It's summer and I'm bored so I've been playing around with some old skis.
The idea behind the test is that I found the old Blizzard GS 190 27m boards where a bit too hard with a somewhat damp feel. So I got a piston plate and installed in on one pair, I had set it as a soft flex at first, but the skis became too soft. So now I've changed it to a medium/hard flex. here is what they look like
This is the standard FS power plate, note how the arms still allow some flex at the shovel but not much in the middle
These are the close ups of the plates, note where the upper line (level 0) crosses the bindings, the piston plate allows more flex
