My Gravity Shift has been resurfaced too many times to count. I bought it used from a friend for $30 after he had a pin-over-fingers drill he liked, but didn't love, so he tried a ton of different surfaces. He still didn't like it so he plugged it and went with a 3x3 layout, and hated that. I plugged it and went with almost the same exact layout he started with, and put some fresh surface on the ball. It still has labels, but just barely. This ball has been plugged twice (I actually track over the plug material!), has countless games on it, and has been sanded a bunch with only one hot water bath over a year ago. And it still is one of my favorite balls for oil when I keep some surface on it. I used it in the USBC Open this past year with good success. It was my go-to ball on longer oil in my summer PBA Experience league. And I bowled a 300 in league with it just three weeks ago.
What surface did you have on the ball before it was resurfaced? What surface is it at now?
