First, thanks for all the answers posted, I'm considering all comments about resurfacing, redrilling and buying a new Wizard.
Now, I took my AI to practice last weekend because I said it's not possible that my most expensive ball is not working. I started practicing with it, three games of 170 then finished with 210, 200 (if I don't miss a couple of easy spares = 230, 210). I finished practice standing at 27-28 which is not my comfort zone (17-22) but managed to make a decent score the last games. Lesson learned: if inexperienced bowler then don't take to league a ball that you haven't used in a long time. I learned the hard way as last week shot 490 and yesterday took my BigTimePearl (which i can play my comfort zone and have more experience with) to score 610. Well, such is life.
