I have found the GF 4.5's Cap, although not to our size, has its snap tendency in hard elevator throws. That's why I think I'll give'r a try. It just may be the solution. Nobody will know if the elevator stays neutral, lol!

Oh BTW, I did that fiberglass work at the cockpit/ turtle-deck junction right around to the bottom and the aft bulk. When the canopy is on it shouldn't move. Thanks for that, drifter!
