I had the opportunity to buy a pair of GS skis for basically free, but they were completely flat.
Now, I know next to nothing about actually mounting skis. I've only ever bought ski packages, everything included, and had my shop install them.
From what I understand I can have the bindings installed flat on the skis. However, should I buy a piston plate? I'll mostly be using the skis to either practice GS, freeskiing groomers and maybe the occasional race (not FIS, no equipment regulations to follow).
I have Googled it, but I can't really seem to find much information that indicates why a piston plate is useful, and why I should/shouldn't get one for these skis.
edit: I also had another question! If I DON'T buy a piston plate, does that mean I can attach any binding to the ski, not just one that has to be compatible with the plate that I buy?
