I just bought a new Roto Grip Halo two week ago and get it drill it. I used a layout 50 x 4 1/4 x 70. so I used for two weeks on my regular league and definitely no carry at all. I was on the packet all night and leaving 10 pin and some times 8 pin. I used the factory surface finish the 1st week then next week I polished because I want little more length, but no changes at all. So my question is that it could be a bad layout which is pin down on this ball or probably not match my game. I weight the ball and it have a difference between top and bottom of 1.80 oz and .80oz to left to right. do you guys think that I probably need a wight hole on this ball. I know the rules change but seem like we have until 2019.

Any suggestion ???


Speed 15 mhp
PAP 4 1/5 x 1/2 up
70° axis rotation
not sure about Axis Tilt
14 lbs bowling ball

Thanks Much !!!

To help with layout advice I need to know, speed, revs, tilt and rotation.
Check out this link to help determine your release specs.

You are very rev dominant.
The layout you have on the Halo is more of a midlane layout

I suspect that the ball is burning up early and hitting the pocket flat.
Surface adjustment was not successful as you already tried.
Ideally you would want a P1 balance hole to effectively increase the totals but you don't have finger weight to work with.
With a balance hole for this year you need to keep the static weight within the 1 oz limit.

Without a balance hole you can utilize the 3 oz imbalance of the new rule.

Short of plugging and re-drilling I suggest drilling the ring finger 4" deep.
Drilling the ring finger deeper will act like a P1 balance hole reducing the flare and effectively raising the totals.

If you choose to plug and re-drill I suggest a low flare layout ..... 85-2-55

That halo has a monster cover... and unless you have an appropriate amount of head oil it will start flaring early and hit like a marshmellow.

I have a similar layout and what helped the most was taking the cover to 4k.

It stopped trying to flare early and retained energy on the backend. It still needs a LOT of oil to be good, but you bought a monster hook ball using it on the correct conditions is key.

Just my .02
