If most of your scores are typical of what you show here (the last game much lower or a fall-off on the last two games) you are indeed a victim of changing lane conditions, as you mention. The first adjustment I try is to move one board right w/my feet (for a right-hander). If that doesn't work then I go back to the original position of my feet and I trade two-and-one, e.g. move two boards right with my feet and one board right with my target. Other adjustments I have seen mentioned on these posts involve lowering your ball position slightly --- to take just a little speed off the ball and allow it time to get that extra "rev" you need to change your angle of entry. Another possibility is to move back on the approach 6" from your normal starting position -- again, to allow for a slight change of angle entry to start "kicking" out that ten. With regard to your 10-pin spare problems, I suspect that your new resin ball hooks more and it's causing you "fits" on the spare attempt. Have you had any success using your straighter (presumably) urethane ball on the 10 pin??? Finally, practice makes perfect ---why not spend one game of practice on the 10 pin?? Forget the full rack on your first shot -- just line up and shoot for the 10. If you dump it in the ditch, so what?? It will still be there for the second attempt. If you make it on the first shot, good!! Line up and try to make it again. 10 frames will give you 20 "practice" shots at the 10 --- you can also try diffferent lines on the 10 on your practice ---- maybe you're on a bad line for the spare where it's all or nothing -- if you throw a perfect shot you make the ten, otherwise it's a miss..... You might find a little practice will lead to more enjoyment and more conversions during your next league session.
