I have seen people using some layouts with Weight Holes about their fingers ex)

weight hole is the "X"

oo

can some one explain what this does as far a ball reaction and how to lay a ball out like this.

I wouldn't recommend putting a balance hole in this location, very likely to flare over it. I'm not sure how it would affect performance, but if I had to get rid of finger weight I'd put the hole to the right of the finger holes, between the holes and the VAL. The PBA plastic ball layout (see link below) does use a high balance hole, but it is further right than your drawing. -- JohnP

this would/could be a weight hole for a full roller

I was just thinking that, but wouldn't the pin be "down" for the full roller? You playing any golf lately?

Possible, that would eliminate the flaring problem. But most full roller layouts keep the cg close enough to grip center that they don't require a balance hole. Would a hole in this location enhance ball reaction for a full roller? I suspect it's more likely the PBA plastic ball layout, which can be used with any pin-in ball. -- JohnP

A friend of mine had an evolve with the pin high above the fingers.. it had a longer pin to cg so he didn't need a weight hole. He drilled a vital sign with the same layout but a shorter pin, this placed the CG over the fingers... he had a weight hole over the fingers and didn't flare over it. The ball actually rolls pretty well for him.

John,

A few years ago we drilled a full roller, and at Ric's suggestion put the weight hole above the fingers. It gave our full roller a more aggressive entry angle than before. You need a ball with a longer pin to make it work.

That's interesting. I don't drill for many full rollers, but will keep it in mind. -- JohnP

If the pin is above the fingers and the weight hole is above it...it would be reshaping the core in such a it would lower the diff and raising the RG...you do take a chance on flaring over it depending on the bowler's rev rate. On a plastic ball I could see it being similar to a strong weight hole being approx 6 3/4" from the core.

I have a ball with this layout and I don't have a problem with flaring over the extra hole. Then again, I don't have Osku revs, either.

Raising the RG and lowering the differential should weaken the ball reaction, making it go longer and break less. Maybe that's what they were looking for. On a standard full roller layout if the balance hole were a little further right than the drawing shows it could be on or very close to the MB, that might strengthen the reaction. -- JohnP

The strongest place for a weight hole or mass bias placement on a full roller would be above the fingers in an area between both of them. As far as a weight hole, 6 3/4" from grip center at 6 o'clock would be the strongest placement. It's 45 degree from the track.

Ive seen it a few times with short pin bowlingballs where they decided to go pin up and had too much top weight. You would want to put the weight hole away from the side of the ball it tracks on. So for a right hander closer to the ring.

Its a layout that a lot of extremely high rev bowlers use to create a long smooth reaction. You don't see a lot of them because it makes the ball roll weak. Usually, its the result of excessive finger weight.

Did you switch to talking about a 3/4 roller in the second sentence? If not, I don't understand. -- JohnP
