First off my old Remix cracked, and I got a new one. I do think it is different that my old one, but whatever. I usually put knee blocks in my river runners after my knee slipped above Bouncer one time. I am thinking about glueing foam under the front part of my seat to raise it up slightly. Does any one do that, and will it hurt the boat by creating a spot with no give? What else do you guys do on your hard core river runners to create a tight fit.
