I think the direction of a spinner shot is fundamentally similar
to a hook one, i.e. both are determined by the path of the
armswing. It's important to keep the shoulders perpendicular to
your ball's path, as well as letting gravity do all the work.
Something I'm still finding very hard to do...
Also important, is your placing and drift. Placing is calculated by
counting the number of boards between the sliding foot at the foul
line, and the board at which the ball passes through at the
foul line.
For example, I'm a rightie, i drift right 4 boards
and have a placing of 6 boards. Should I start at
the approach at board 20, I should drift to board 16, and release
the ball over the 10th board. In short, I stand at 20, aim at
10.
Say I stand at 30, aim at 10. To get to the 10, my armswing will
deviate from it's gravitational path to the right, for
compensation. I found that this affected accuracy and consistency
quite a bit.
Solution: Still standing at 30 and aiming at 10, twist torso to the
right and keep it there throughout the swing.
Result: Armswing's path kept straight, AND being able to pass
through board 10.
Drawback: EXACTLY HOW MUCH TO TWIST TORSO?!? Sighhh... trial and
error I guess, plus lots of practice.
Anyone employing this method? Uncle Fox recommended it, and I'm
still struggling to improve. The theory looks sound on paper
though.
To make sure I was following through on my shot, he also asked me
to finish the release with my hand beside my ear. Right hand, right
ear of course.
