Gene, you state that bowling has become more mental than physical. I can assure you that bowling has become more mental, but physical has no less importance than it ever did. When you show up to bowl a tournament, I can assure you that somebody has the right ball, line, and is mentally ready to beat your butt. If not let me know where you live, as I would be willing to move! My advise is: Always assume that you are bowling well. If your not scoring well it is because of either the wrong line or the wrong ball or both. Of course, this isn't always true, but you should approach your bowling this way, or you will be toooooooo slow the change. Thus negating your chance to cash. I couldn't imagine going into a new house to play a match without at least five balls. I usually pack eight or nine, counting a spare ball, and a polished urethane. How to read the lanes is the problem. Start with a ball that you would use on a medium, wide open shot. During warm up, find any out of bounds. If there is out of bounds, move deep enough that it isn't in play. After a ball or two you should be able to know if you need medium, dry, or heavy oil equipment. This reduces your selection of balls at least in half. I usually start with a ball with an aggressive drill (label leverage, stacked leverage, etc). The reason for this is: If scores are going to be through the roof, I need aggressive equipment to keep up. If I start with a ball that is going to the correct length, but is out of control, then I would either go to a milder drill or a more e aggressive cover. If flat 10's are showing up then figure the cover is too strong. If you are ringing 10's either the angle is wrong (line), or the cover is too polished (the ball is still hooking at the pins). My first thought about ringing 10's, is to go to more cover and play the same line. If I can't score, and I see everybody else having trouble I go to urethane. My theory is I'm more accurate, thus if it isn't a carry contest, I can win with urethane(this isn't always true, but it goes back to my original approach, that if I'm bowling poorly it is because of the lane set up). I hope this helps. I know there is pressure (mostly self imposed), that if you change balls, you have to score higher, or you look foolish. Remember, that when you lose you always look foolish. I try to win, and don't care what anybody thinks about my bowling. If I change balls five times, and don't win, I still just didn't win. If I'd have stayed with the original ball the results would have been the same. At least I tried!!!!!!!!!!!!
