Hi, what would the best rail height be for Championship tour edition K66 cushions? I have an old Big 'G' with 1 3/4 high rails. The new K66 I had put on it barely gives me 3.5 lengths rebound hitting a ball real hard, though the cushion nose is right at 1 13/32, cusions glued on solid and the rails are bolted down solid. I'm thinking this cushion/rail combination just isn't a good one. Any thoughts? Thanks, Steve
