You aimed this at Dave but everybody else jumped in so I might as well too. There are two reasons they spin bullets and re-entry bodies: the first is because gyroscopic effects help stabilize the body, and second is so that asymmetrical aerodynamic effects due to surface irregularities or a cg that is not quite on axis are averaged out in the flight of the body and you end up with a relatively predictable trajectory. An unbalanced (or out of round) ball may 'wobble' in flight due to the spin but the effect on the trajectory should be almost nil.

If they are saying that a ball being out of round may cause it to come off the club face different than it would if the ball were perfect - I'd give that a maybe, but I'd be surprised if you could isolate that effect from all the other things going on when the club hits the ball.

As far as putting goes. If we putted on ground slate there would definitely be an effect, or if we were all really precise putters it would matter. Personally? I always pick asymmetrical balls and align them so that it will help with the break and roll into the hole. I'm down to an average of 36 putts per round by doing that.

Regards,

Alan

Dave,

Do you think there is a way to orient the ball to fight the slice?

That was an impressive review, wasn't it? I'm tempted to get one myself.

A couple of things they said comparing the spin balancer with the static

(Epsom salt water) balancing:

  * They said that the improvement was considerably more significant
with
the spin balance.

  * They speculated about the cause of the different balance points for
dynamic and spin. I'm not sure I agree -- haven't looked at the details
--
but it's the most plausible I've seen yet. My own paraphrase of what I
think they were saying: static balancing finds diameter on the ball with

the greatest light-to-heavy difference, while spin balancing finds the
heaviest great circle on the ball.

I'm pretty sure I understand what they were saying. They definitely did
not
say that orienting the ball this way will CURE either a hook or a slice.

They said that aligning it this way means the golfer's swing path will
match the balance plane, assuming a slicer swings outside-in and the
hooker
swings inside-out. So that way, the spin imparted will be consistent,
neither reduced nor exaggerated.

Cool!
