Poindexter.V2You could get a release test done and ask them to write down the force values for you
OP this is a good first step. They'll take a look at the bindings before accepting them for testing to look for cracks in the plastic and other cosmetic damage. I've been told I need new bindings by a few shops due to this cosmetic damage so just by visiting the shop you'll kill to birds with one stone. Whether you accept their suggestion is up to you, I've continued to ski FKS' that have cracks in them because I'm a degenerate.
