I have been playing around with throwing a separate spare ball (plastic ball) over the past couple seasons. Overall I have not seen a big increase (if anything, maybe a slight decrease) in spare percentage.
For me, it seems as if no two balls I own feel the same. Yes, they all have the same spans, pitches, etc... but still they are all just a little different. To complicate things more, my thumb never seems to be the same size (night to night) and often changes throughout the night. As a result, I will get comfortable throwing one ball for strikes...and at some of the middle lane spares. Then inevitably a few frames later, a spare will show-up where a plastic ball would be beneficial (10 - pin or 6, 10 etc). When I pick up the spare ball, no matter what I seem to do, it feels a little different. Now I'm not sure whether there is an actual difference between the two balls, or if I get distracted thinking about the difference in feel, or whatever, but sometimes it definitely causes the spare ball to either slip off my thumb... or more often hang up on the thumb a little. As a result, the shot tends to be pulled one way or pushed out the other. Gets to be very frustrating. I feel I would make 99% of my spares if I had a consistant feel.
Lately, I have been leaving the plastic ball home and just flattening out my strike ball. This seems to work moderately well, but occassionally I don't completely flatten the ball out and it hooks a small amount.... again causing it to be off target.
I'm not sure whether I should abandon the spare ball completely or practice more with it to get the comfortable feel. Anyone else have the problem? Any suggestions?
