Interested in replicating the arcing reaction in 3 balls each drilled CG-Axis w/balance hole on axis.

Tried plugging the hole on one of the balls for the rule change. The ball is still quite useful but lost some continuation and the arcing motion, reaction now is â€œalmostâ€ like a pin-axis drilling. Other than surface adjustments the only thing I can think of trying on this ball is drilling the thumb-hole deeper. I like my solid (Forest-Green Quantum) so much Iâ€™m leaning toward not plugging it until Iâ€™m more confident I wonâ€™t ruin it.

Saw an interesting YouTube ball video with 2 bowlers where the lefty bowler used a small drill-angle (20x4.75x55) on asym balls https://www.youtube.com/watch?v=odCg5__tMEc called it forward roll layout.

Anyone have experience or thoughts about a smallish drill-angle producing a CG-Axis like motion?

Likely my last post on this topic because I have a partial answer to my topic question:

Had my PSO drill a Pyramid Pathogen Plague Pearl (urethane asymmetric) with a 20x4.5x45 layout. On a medium oily condition, OOB surface and no warmup, this combo out performed my cg-axis Forest-Green Quantum (which I really like). The Quantum had a bigger arc but this urethane ball carried much, much better with a small arc followed by a strong forward roll.

I believe this layout would have been bigger and rounder with a different surface but I donâ€™t care with the way this combo turned out. Will probably drill another asymmetric ball with a small drilling angle layout.
