Ours has a little piece of plastic or glue inside that rattles around occasionally . I could send it back or just repair it myself alot faster. I was going to use a shouldered juma plug, then re-drill, tap.
You think phenolic is better in this circumstance?
I think you have to weigh what you or anyone thinks they know versus a product that may have a warranty on it and if that change will void it.
Chasing the threads with a larger tap is pretty safe.
CHANGING the insert may void everything.
I have one cue with 3/8-10 and two with radial pins. When I compare the threads the radials look so much nicer. I’ll never buy another cue that doesn’t have a radial pin.
I have three 12.4 Revo’s. John Lavin’s Defy 12 shaft was as smooth as my Revo with less squirt. I had a good night shooting with that shaft, that’s why I want to see if it was just a placebo effect. Funny thing is, I played a ball or two better the first six months I played with the Revo.
