On your 13mm wood shaft, consider changing the ferrule....metal might do the job.Well I'm from the country where piramid is the major billiard game. So I do know something), play, teach in this game too because there is more interest to it here. For this game I do have a piramid cue with traditional spliced construction.
So as I enjoy playing pool more ... I do have my own preferences and cues when it comes to this game...
A few times I had some fun with pals playing "pool" using pool balls on 12ft piramid table with those pockets ... but it was never the other way around). Nevermind...
Good luck with whatever you're looking for).
For players that are gung-ho about no squirt....massé is a problem also.
The trick is to get a shaft that is user friendly, where squirt and massé are acceptable.
I have played a little with the big balls.
