After about 4 years the rubber on my GC1V turned dead on the short rail where the back 2 balls hit after the break. And actually I thought the rails were a little dead right from the start. I contacted Pat Sheehan out of Portland and he informed me that Brunswick is having the superspeeds made overseas. Dirt is being used as a filler [to save money I guess] instead of latex. I sent my rails to him to repair and when he tore them down the rubber on my short rail crumbled off in pieces. He installed K55's and I'm reasonably happy with them. I'm curious though if anyone else has run into this problem and and what were the results? Don
