Question about tracking
« on: September 10, 2008, 09:24:41 AM »
I have just been reading a training manual given to my brother for his work at AMF, and I chanced accross a diagram showing different ball tracks.

Now I always thought I was a semi roller, but this manual refers to my ball track as an invertered track. The invertered track is where the track is very close to the fingers and about 1-2 inches away from the thumb.

My questions are....
1. what causes a bowler to roll an invertered track
2. Is it a bad thing
3. If it is a bad thing, what changes do I make to be a semi roller

I used to roll a semi roller track a few years ago. I tracked a little low as I probibly spun it a bit. A coach told me to get my hand behind the ball and stop spinning it. I worked very hard and got my track higher and he was happy that I had done this. I feel that my carry is not as good as it was 4 years ago when I was tracking differently. I have more troubles on drying lanes then I used to. I have tried to move my track back to where it was but with no success.

Any sort of input into this subject would be great as there are close to no one out here in Australia with any sort of knollage about this sort of thing

First, be sure you are looking at the first track ring - that's what determines your track location, not the later flare rings.  If you have a non-flaring ball check the track location on it using your strike ball release.  As you describe your track, it is an inverted semi-roller (or 3/4 roller).  The inverted part simply means the track is further away from the grip centerline at the thumb than it is at the fingers (or, it angles toward the fingers instead of away from them).  That will also give your PAP location a down dimension instead of an up dimension.  I have been told that which finger exits the ball first determines whether the track is inverted, I think if the ring finger exits first the track is inverted.  That's not necessarily a bad thing as long as you're satisfied with your ball reaction.  See the website below.  --  JohnP
