I build cues, but I quit playing because of eye problems. Lot of break cues available. Don't know what to recommend. A house cue would probably work well enough.
My guess is you are breaking with your playing cue. Very hard on the tip. Best to break with a cue dedicated for it. A good hard tip will hold up better. You may also need a better quality tip on your playing cue.
A way to check for straightness without a table is to stand the cue up on the bumper.
Hold the ferrule loosely and spin the cue while looking from the tip down.
I screw the cue together first. Put the tip on the table and the buttcap on the cushion. With the cue elevated you can really see what is going on. The same can be done with both pieces. Roll them separately elevated off the felt.
I have boxes of le pros from the 90s still good. If you squeeze them side to side with pliers that will tell the tale. If they compress easily they are probably not good. If they are firm they are good to go.
Gorgeous cue. Always loved Macassar. I have built over fifty Macassar cues since 1983. None with figure like this. I was inspired by Kersenbrock's cues. All of his builds I saw were from Macassar. Great playing wood. Built by a fantastic artist.
A good cuemaker can alter the joint threads on any shaft. That is one option. The cue pictured is very nice. Curly and Tiger maple are the same thing as far as I know. Good luck finding your magic wand.
