Inverted Track
« on: March 22, 2005, 05:37:47 AM »
Apparently i throw the ball with an inverted track, i still dont understand why.  But im curious to what it means as far as my ball reaction, and how it would effect my PAP corridantes.

I have been googling and browsing sites but havent found any deffinate info, one of the sites had it listed as a  "cranker track"

Can anyone shed some light on this subject for me?

Great info Bob, i think that may be the case for me.  The ball or balls that im throwing are a Classic Zone and an Impulse zone, both of which are Assymetric, and have a defined PSA. It may be where im hitting it in the release but i cant seem to figure out why. I think i come out of the ball right, but eh.  I have some footage that i have posted over the past 2 days, of my release and the ball reaction i get.

Maybe i will take a symetric ball and mark it with tape to see how it reacts on the lane as well.

Its odd, looking at the video's im told that i have an inverted track, but when my ball comes back on the return it seems that i have a very LOW track, oil line +3in away from my thumbhole.

the latter being slo-mo and frame by frame, to see where and how my hand hits the ball upon release.

Not sure if this will help.  My "normal" release, tested on an old rubber ball that does not flare, is that of a high tracker - the track is within an inch of both the thumb and finger holes.  Using the same ball and a release change, I can get the track to invert, moving the track about 3 inches away from the thumbhole while maintaining the same distance from the finger hole.

Wish I had video to show the difference in the release.  With both releases, I use the cup-and-collapse or "open hand" release ala John Jowdy.  My coach maintains that the difference is direction of the hand (not the rotation) through the release.  On the normal release, the wrist collapses and the hand continues through the ball (parrallel to the armswing) from behind and forward into the follow-through.  To invert the track, as the wrist collapses in the same way as on the normal release, but the hand moves across the back of the ball at an angle (maybe 30 degrees) to the armswing away from the body.

Rhono - Yes, with an inverted track your PAP would be below your grip center.  I verified the inverted track on a ball that does not flare.

Bob - sounds about right.  Without video, it is hard to put into words.  The first release feels more like scooping ice cream (in reverse-motion) while the second release feels more like opening a chinese fan underhanded.

My understanding was the inverted meant a PAP below grip center.

I see a change going from a low flare ball, (tracks 1/4" to 1/2" from both fingers and thumb), to something with flare (tracks noticably further from thumb). I tend to loft the ball a bit and assumed that the difference was due to flare occuring between release and oil.



Rhino,

Just like you, I loft the ball as well.  Track is inverse as well (4 3/4 x 3/4 down).  My game is leans heavily towards the use of pearlized balls.  Do you find the case to be the same with you?

ok... so based on my video's it may appear that my track is not initally inverted, but could become inverted after some flare is introduced.  

Ok, im much much more confused now.

This is all to confusing, becasue as i said, the only oil rings i find on the ball are very LOW in the track.  But then watching the ball rotate the track is inverted, it appears that i have a normal track taht is very low. According to the oil rings i find after throwing the ball.

Moe - Do you suspect you know where your PAP is?  If so, you can put a big piece of white tape on in and toss the ball through the oil, even with a flaring ball.  If the tape doesn't seem to move (rotate around) for the first 15 feet, you've found your PAP.  After that first 15 feet, the rings (flare) on the ball migrates farther and farther away from your initial (release) track, and the tape will no longer be on the axis around which the ball is revolving.

No, im not sure, i have yet to find it or have my ball driller find it.

I have a recharge drilled for lengh, pin above middle finger, that would be better for attempting to find my PAP, with this ball the pin to pap distance being greater than my classic or impulse would greatly reduce the ammount of flare, correct?

So i may take a trip to the lanes tonight and attempt to find it. do i need a straight piece of tape, or would a pice of thumb tape be good enough?

Any 1-inch piece of square tape will work, just make sure it sticks out from the color of the ball.

Found this while looking at one of LL's posts, see if this helps

An inverted track would be the dotted line furthest from the solid line in the first picture.

Easiest way to determine if you are inverted or not:

Take any ball, throw it in the oil so you get some flare rings.

looking at the fingers up thumb down, Find the "bow tie" (the area where all the lines meet) and look above it. The oil line on the far left is your initial track. Measure the distance from the thumb and the distance from the fingers, if the distance from the thumb is greater, that means you are inverted.

Very few people are inverted: Reason being, its hard to release a ball with an inverted track. Your fingers usually are in the ball for a long time after the thumb comes out to make your track inverted.

I actually have an even stranger release (most of the time) than an inverted track. My first two flare rings always flare over my thumb hole, and they move away from there. It is inbetween a full roller and a 3/4 roller. My driller says he has only met one other guy who does this to the ball, and he was very dominant in the pre-resin era. I get too much lift at the bottom and do not turn fast enough (I turn plenty, usually 60 degree rotation), and it therefore thump thumps the first 15 feet. Off on a tangent, but its related to the topic at least.

I have been bowling since rubber balls were basically it.  I have a natural full roller release but my track on an old rubber ball is about an inch from the fingers and about 2 inches from my thumb.  I tend to get early roll and I do not generally like resin balls unless they are of the particle variety so that I can get my even arcing type of ball motion.  Pearl is the worst resin for me to throw, the general reaction of pearlized balls I mean, too flippy.  When I use the new equipment my track drops down so that it looks like I spin the ball, but I do not have a spinner release.
