Full roller?

[dewatkins]

What is ment by saying I am a full roller?  Does that mean the track goes between the finger and thumb holes?  Does it mean that the track never gets to any of the holes?  How do I know if I am a full roller?

Just as you said, full rollers track between the thumb and finger holes.  For a righty, I believe the track goes from the left of the middle finger to the right of the thumb hole.  Even for a semi-roller (most people nowadays), the track should not clip the holes, though it does for some (me, with certain balls).

As I understand it, full rolling happens when you rotate your hand from the outside of the ball to the inside or behind it at release.  The FR I know does that.  Semi-rollers either stay behind and rotate to the outside (see Mika and many others) or rotate from the inside out (PDW, PA, Amleto).

Yes

That depends on 1.  Exactly how you release the ball.  Some full rollers clip a hole on their initial track.  2.  What type of core the ball has and how it's laid out.  If it's a plastic ball with a pancake core, the track won't flare and all the track rings will be the same as the initial one.  If the ball has a dynamic core, the track will flare.  If the ball is laid out with the pin in the normal area for a 3/4 roller, the track will flare into the thumb and/or finger holes.  Full rollers should use special layouts that cause the flare to go in the opposite direction so it flares away from the holes.  You can view this type layout by looking at the drilling instructions on any manufacturer's website.  The one you're looking for will be labelled "Full roller layout".

Look at the oil rings.  If your initial ball track is between the thumb and finger holes, you are a full roller.  --  JohnP

A full roller can also occur when you play a ball with a strongly broken-back wrist, no hand rotation needed. That's what happens when I make my spare shots. Normally tracking high on normal shots with a straight wrist, I get a  full roller track on my spare shots. I am not sure if a ball would hook much this way, but there are full roller drillings which tend to such a release and exploit the core's dynamics.
