Of course if other factors are involved, then the discussion
about inserts would be void. As common sense dictates, I am working
on the assumption that, with all other factors being held constant,
inserts do not increase a bowlers revolutions by
that much.
No grips allows you to feel the shot and gives you a better read if
you 'caught' a shot or not. In todays game when throwing revs, the
idea is not to lift the ball anyway, just watch Kelly Coffman, Pete
Weber, Robert Smith, Tim Mack etc etc all those guys palm the ball
into the front part of the lane and through good timing and a nice
whipping motion with there wrist, they hit the ball very hard
without lifting the ball at
all.
Strokers lift the ball, power players palm it. Most power players
who are any good tend not to use grips. All true power players put
the ball down relatively early because of this.

I know what you're getting at - like how an axe delivers more
powerful blows with a heavier head, right? Unfortunately, you are
discribing the theory behind the high RG ball. A high RG ball has
its weight distributed outwards, closer to the cover than the core.
Using the axe analogy, the blow is more powerful, but initially
swinging it would be more difficult than if the head was
light.
High RG balls have will tend to "rev up" more after the turn, hence
giving a more angular breakpoint, but are also more difficult to
rev off the hand.
Another consideration is that the maximum finger weight for bowling
balls is only 1 ounce, and this is easily manipulated through
drilling, so the block would be too small to be useful
anyway.
In Singapore, many bowlers actually CANNOT use so much finger
weight, because the more finger weight one has, the more length one
gets. Because a lot of people here are "hook-challenged", many ball
drillers actually remove their finger weights by drilling very deep
finger holes. If you look at the balls of certain "hook-endowed"
players, the finger holes are only deep enough for the fingertips
and no deeper than that.
