I know I ask a lot full-rollers. I'm not one myself, but my brother and two of my friends who are pretty high scorers are full-rollers. I've been trying to help them add axis tilt, but they all average 10-40 pins higher than me so they're not easily convinced that they're doing something incorrect or could be doing something better.
Anyway, my question is about this statement by Mo, "The key is the axis tilt! A ball will continue to hit as long qs the axis tilt is > 0* when the ball hits the pins, no matter how much axis rotation the ball has."
When I'm talking to my brother about tilt I say, "You need tilt for the ball to have hitting power" and he just laughs at me because he blows the pins off the deck with no tilt all the time. Now the few times he's been able to release the ball with tilt, using Mo's standard no thumb finger pitches, the ball does react differently and does seem to hit harder.
My question is why do their ball's seem to hit without tilt? They are all three high rev, high speed bowlers. Is it because of that? If you have 18-20MPH ball speed and 350-400 rev rates do you not need tilt? How can we correct thier lack of tilt? Two are no thumbers and the third is a half thumber. All three come way around the ball and release it with their hand on the side of the ball. There is a video of the two-hander in the coaching section.
Any info is appreciated. Thanks.

Re: Full-Roller Question
Have a look at this.... http://wiki.bowlingchat.net/wiki/index. ... all_Motion" onclick="window.open(this.href);return false;
Note that at the end of the hook phase you have reached your MAXIMUM RPM!
Now given the info you provided if a bowler with say 19 mph speed off his hand AND he has transitioned into the end of he hook phase he will be at just over 600 rpm at that moment! If he is about to hit the pocket at that moment not much is going to stand up!
Speed translates into rpm at the end of the hook zone. It's the same for low (300-) and high rev players (400+) as well provided you've made it to the end of the hook phase right before impacting the pins.
So no you don't need tilt to have hitting power. Tilt only lengthens the roll phase prior to hook out and the longer you take in the roll phase the less hitting power and rpm you'll have at impact.
I hope this helps!
