I was watching the binding mounting video on snowprofessor.com and they suggest using a rubber gasket under your binding when you mount it, I was wondering if most people do that, or don't bother with it?
My Ride EX bindings have a very thin piece of rubber adhered to the base plate. I'm pretty sure it's too thin to really do much dampening but I'm thinking it helps then stay in place. Seems functional and would add something myself if they a) didn't have them alredy b) I had stuff around to use.
I only do it because SnowProRick gave me the old gasket that was pre-cut for his wife's snowboard. It's definitely optional...but is nice and does keep your topsheet pristine (good if you plan on reselling your board).
rome bindings come with them. They say it helps reduce chatter and improve feel. I also seem to remember, way back, something about the gaskets improving flex and lowering the possibility of board breakage.
