Is pin below fingers drilling "usually" better for higher speed but low rev. players compared to pin above fingers?

Quite a few times I read that the position of the CG did not matter much. But I just read from the LaneMasters drilling inst. that the ball would hook more with the CG kicked out. Could someone clear this up once and for all?

Thanks a lot!

Pin below fingers will help the ball rev up better in the mid lane. I have low revs, so I use mostly pin under fingers, under bridge, etc. drillings, unless the ball has a low RG and very strong coverstock, then I will move the pin up.

As for the CG position thing, different people have different opinions on this and there have been some pretty hot discussions about if the CG matters or doesn't matter, so I can only tell you to do what you feel works the best for you there.

In a short answer, yes.

  As far as CG placement, the jury is still out as to the effect it has.  Some manufacturers say it has NO effect, some say it does.  Some say it matters only in relation to whether you end up needing an x-hole to make it legal and cg placement can be used to allow you to use either a flare increasing or a flare decreasing x-hole.

  The "reason" that pin below bridge "usually" works better for higher speed players is that, each ball has an RG rating.  What that is, is a rating to tell just how far from the physical center of the ball that the weight is rotating.  The higher the RG rating, the further from the center the weight is rotating.

  Think of it in relation to an ice skater.  When they spin and have their arms outstretched they spin more slowly.  When they have their arms tucked in they spin more rapidly.  Outstretched arms INCREASES the skaters RG and tucked arms DECREASES the skaters RG. The lower Rg makes the ball a bit easier to rev and also lets it pick up additional revs easier than a high RG.

  Low RG balls tend to roll earlier and more smoothly.  High RG balls tend to go longer and hook later.  Pin below the fingers gives a lower post-drill RG rating than a pin over bridge would.

I'm really tired of the whining, so, JUST SHUT UP AND BOWL!

whether a pin is above or below the fingers does a few things.

basically when its above the fingers it will react to friction faster

BUT

a pin below the fingers will transition to a roll/hook earlier making the
ball most likely arc rather then skid/flip


I wouldnt worry about cg. i believe it does have a difference on ball reaction
but its not much and not enough to worry about.
