Title: Span Length Question
Post by: TheGom on August 25, 2015, 11:25:43 PM
Have a one year league bowler on my team who was fitted last year for a new ball.
Finger tip and thumb slug.

If his span is to big what type of results would we be seeing from that?

Based on the Wiki fit I feel it is 3/8" to long as he only gets 3/4's of his fingers tips into the ball. He's been throwing a slight back up.

Is the span hurting his chances to learn how to throw a slight hook?

Thanks

Depending on how hard he throws and how often, he could just plain be damaging his fingers ad his hand, never mind about learning to throw a hook.

If he needs to learn to bowl, he should see a good coach.

Also, if he doesn't know how to throw a hook and he just got a finger tip ball drilled, he may just not know how to throw a bowling ball, how to seat his thumb and his fingers, how to hold the ball, hot to release it, etc.

Was the ball drilled by either an IBPSIA certified pro shop or by a good driller (that you are aware of)?

Thanks Charlest, yes the person who drills my balls did his....not sure what happened as I was not there for his fitting. His speed is about 16 at the back of the lanes with a 14lb ball but he is never in the dry area of the lane. He is a head pro at a golf course so he has some ability with eye hand.

I just think that he is trying to hold on so to the ball with that span so much that it hampers his ability to learn a proper release.

Have him put his thumb fully into it's hole and lay his fingers over their holes.  Keep the web between the thumb and index finger relaxed.  The gripping edge of the fingers should fall half way between his first and second joints.  --  JohnP

 Place his thumb in the thumb hole and somewhat relaxed place his hand/fingers over lapping the finger holes...eliminating flexibility the appropriate crease should direct the finger hole

More "guru" mumbo jumbo from Rico.

Quote "eliminating flexibility the appropriate crease should direct the fingerhole"      Really???

Take the advice of JohnP   Maybe consider stretching the persons thumb/hand  web before measuring

A. Flexibility plays a HUGE part of the span and B. It was supposed to be dissect...

Thank you for your GREAT advice...

Thanks for both of your comments....JR, hard for me to understand your post. "The appropriate creases should direct the finger holes"

First off, what are the appropriate creases? Next, what is direct the finger holes? Maybe you meant directly over the finger holes, but without knowning what the appropriate creases are, I am lost. Sorry

Thanks John,

I did this last night...it was just past the last joint crease on the finger tip side of the crease, so about 1/2" to long.

We will get it fixed, but I am more interested in the effects that it has on a person when the span is way to long....to me, it seems that it would add a ton of tension since he is gripping the ball to hang onto it. Hard for it to come off the hand properly and hard to apply what people are telling him about proper rotation.

Thanks

If it's a finger tip grip the last joint/crease should dissect the gripping hole...

If it's a finger tip grip the last joint/crease should dissect the gripping hole...

So, wiki says the grip edge should be between the two creases and you say that the last crease should divide the gripping hole in two....is that correct.

Can you explain why you feel this is a better fit please for my own knowledge because I am between my creases and had issues with a span longer than this in the past.

Thanks

In between the creases is vague...if the crease or knuckle splits the finger insert it is closer to precise
This is also eliminating flexibility issues...minimal flexibility can decrease or shrink the span

There's very little difference in the result between Rico's procedure and mine.  Mine eliminates small variations because of the size of the finger holes.

Gom - Don't wait to get the spans fixed.  He's probably not putting his thumb and/or his fingers all the way in the hole with the spans that long.  --  JohnP

One more thing to make note of; is he wearing any type of wrist support?  A lot of wrist supports have a strap that goes across the palm of the hand.  You will need to shorten the span about an 1/8" to make room for the strap.  If he does wear one, he should be fitted while he is wearing it.

While your right about being fitted while wearing a wrist device and if it's a adjustable one you should have it in the position you'll be using it most in.

Your not changing the span to make room for the strap.

It's do to the position the device holds your hand. Like the old Gladiator glove, It held your hand pretty flat and rigid.
