I guess I'm old school, too. I'd rather move and keep the ball in my hands that's giving me the numbers (if I could remember what that's like...).
However, I know my equipment well enough to know, for example, that on that one shot, late in the 3rd game, the ball all of a sudden jumps and barely trips a 4-9 after a 5 board move - it might just be time to switch...
but if I have to switch more than twice (once in practice, once during league) - I'm generally in deep yogurt - and the only thing that would help would be to throw two or more balls at the same time.

If winning isn't important,
why do they keep score?
