I actually am looking for a regular old cuetec for this exact purpose. People have hated on cuetec fiberglass cues forever, but those same people often say it’s one of the best dang break cues ever made just not for playing. I wanted to sand the butt down and paint it Matt black. Then swap the tip to a hard leather break tip. Preferably 20oz for me but it’s not a deal breaker on the weight. When I do get it done I’ll be posting picks.
I say try it out and if you don’t like it just swap the tip back. No harm no fouls. You could put some lead tape on it and a rubber wrap over the top of that to up the weight a little. Just my 2 cents.
