Yes. Beveling inconsistencies had/have become part of the problem. I generally preferred minimal bevel, and that seemed to help me hang on to the ball better. And for the first 3-4 years my regular driller was able to drill any ball I brought to him (new, used, older than dirt) and duplicate the others he had done. Almost like the replicator they had on Star Trek.
Then that driller moved away from the lanes I patronize the most and the new pro shop that came in, could only approximate the fit. And lately, even the originall driller ---despite being very concientious and accurate in most every way--- seems unable to achieve the same level of identical twin-ness I am looking for in the balls.
Anyway... among other reasons pulling me back to the inserts, is the desire to regain some consistency from ball to ball. Where that is concerned, the inserts are definitely superior.
In one of the most ironic twists, I went away from the grips because I was constantly changing them by adjusting sizes and styles and even brands. Figured without them, I would have less reason to be making changes all the time. And it worked! For anout 4-5 years, as long as my driller was able to make what felt like exact duplicates going from ball to ball.
But either my ability to communicate what I want has diminished, or the assumptions by the pro-shop people are interfering with my instructions, or .... my hand has changed in some way. All I know is I am returning to the grips for virtually the same reason I stopped using them....the desire for a more consistent fit from ball to ball.
