Put the pin high up above the fingers so the fingers and thumb take weight out of the side of the core. 5 inch or more pin to pap. That will put the axis at the highest RG and promote a skid flip reaction. Of course a 4000 or higher surface helps as well.

Do you have a super flexible or double jointed thumb joint? The current ibpsia method is left in the thumb.. and the ADT is more left because of how the drilling is lined up. My coke can is 3/4 right or more. I can get a great feeling fit with 3/4 right, but I think there are some pitches that don't...

Don't do well with asymmetric balls for some reason. Is there a placement of the MB that will reduce the asymmetry, and make an asymmetric ball roll more like a symmetrical?

There used to be a simple guide telling how adjusting the linear and lateral pitch affected the tilt, track, and axis rotation. I couldn't find it in the wiki section. Can someone post it here or point me to the link?

Might be a bad batch of tape or old.. I recently got some hada patch that had been sitting in a pro shop for a long time . Does not stick like any of the other times I have purchased it.

Try Ron C's magic carpet. That may help you. I would also look at your wrist and where your thumb is pointing. If you hold the ball at your side with you thumb pointing down, the ball should fall off your hand. You might want to have your thumb pitch looked at. You may have too much reverse pitch. G...

For people having issues with tapes sticking to their skin, try Compound Benzoin Tincture.

Pap is determined bey the bowlers release on a NON/Low Flaring ball. Typically I have customers throw there polyester ball or low differential reactive ball. This will give your the best measurements on the first oil ring that is not influenced by core and cover. Thank you Martin Chan Custom Bowlin...

I look at it this way. Asymmetricals give you more options for reactions. A 5 to 6 inch pin to pap on a symmetrical ball will put the ball in a high RG orientation at release, which can create a quick reaction to friction and a sharp hook angle, but the 5 to 5 1/2 inch pin will usually reduce the fl...

Is there pressure on your thumb in the thumb hole at any point? It is possible your pitches are correct for your anatomy, but the shaping is not. Personally I have extra flesh on the top left front of my thumb and causes pressure on the back right knuckle, could be fooled (I was!) into thinking mor...

I'd like to see the technique of you throwing the ball. Seems release issues are a repeating theme, unless I'm mistaking you with another user. 17* of tilt is perfectly fine with most bowling surfaces being worn. Yep, same guy. Same release issues... Just want to go with what the charts say I shoul...

See if you can get to these links.. I know I rotate the ball in my backswing. Coach Jasnau has seen it live a couple of times and doesn't see it as something to correct. He says it is due to my tendons / limited joint rotation in my shoulder . FYI.. I have now gone to a 5 step approach to help with ...

I'm having trouble getting a consistent thumb release and my ball roll and hit is just garbage. My speed isn't super fast, but I just have a very small pocket and don't get the carry that I should. Been trying to bowl with more forward in my thumb and more lateral right, but I think it is just cause...

I'm refitting my hand and trying a new span and pitches. Is it ok for the middle finger to have more reverse than the ring finger? I have a less flexible middle finger joint and need to have more reverse. How will this impact my ball roll? Going from 4 3/4 span (M & R) , Middle 0 L, Ring 3/4 R. ...

This ball was one of the best balls I have ever thrown. And probably the best ball in the last 5 years for me.. But after 6 months the ball is a dud and doesn't react and carry like it did new.

put your thumb on a line around the bottle that is between the index and middle finger. That is how the fitting tubes by Mo are made. I like to look at it on a line between the middle and ring finger, since that is where the thumb hole is.

Do you think it would have enough effect on a slower speed lower rev player to make a noticeable impact on ball motion and carry? I think it would. It really depends on how slow we are talking. I know some seniors that are rolling at 11 to 13 mph( off the hand) with an end over end roll. Put the we...

Just the scale? Or ready to weigh bowling balls?

The premise: 1) Textured white tape in the front to improve the grip 2) Slick black tape in the back to tighten the thumb hole and provide a quicker release My 2 cents, why would you ever put anything in the thumb hole that is shiny and slick to tighten the hole? I don't believe that black tape sho...

Undo the set screws and align the blade so that it will be equal when you rotate it at 0 - 0. Of course make sure your press is calibrated and accurate at 0 - 0. Might be the cutter... might be the press.
