Dear "erriep" and "jmf041"
Just a word of warning about the rubber grips billiard players use. I had a brand new Schuler wrapless cue. I had ordered it wrapless specifically so I could put the rubber grip on. I put the grip on and used the cue once. I put it into my most excellent cue case. My case is (was) a tube case, so that the shafts and the butt slid down into the case, as is usual with cases that don't open along their entire length. The next time I went to get my cue out of the case the rubber grip had made a perfect seal with the lining of the case! It was immovable. I had my neighbor's monster-strong, boxer son try to get it out. He failed. I finally had to use a tin snips to cut through the case. The case was a goner. The only damage to the cue was a fairly bad gash to the cocobolo joint. The rubber grip went in the trash.
I felt like an idiot. A week later one of the best players in the poolroom came up to me and said that he had a secret he wanted to confide to me, and that it made him feel really stupid. It seems he had gotten a rubber grip for his cue and put the butt into his case. I stopped him. "Let me guess," I said. "When you went to get the butt out the next time..." Of course I had hit the nail on the head! And he is a superb mechanic, lives on a farm, does his own repairs, and all that stuff, the opposite of me. But we both had been driven to the same solution.
