So, last week I noticed I lost a bit of reaction on the ball. Not much but a little bit, I had to move a board or 2 right of where I was standing and if I missed in it slid a couple of extra feet. Now keep in mind I have close to 75 games on it in the first month. So, yesterday I got asked to sub. I decided to stop by the proshop on my way home to change and drop the ball in the rejuvinator to see what would happen. Last week I also ran the ball with a 3000 Abralon pad again but it did not help. Well I get to the lanes and the proshop tells me the ball is ready and it bled for 1.5 hours.Well the answer was right there last night. Full reaction back to the way it was at first. If I had not had the ball hang on my thumb late in game 3 I would have had another 800 with it. I did shoot 280,279,230 with it for 789. SO my advice to you is to pay close attention to the amount of games on the ball and the reaction. Any slight change should give you a clue to get the ball to a proshop for some deep cleaning.
