For me, pool is a game which is highly inflicted by the way my head is affected and "used" or distracted....
If I have a tip which is not round and something is sticking out over the ferrule, it's enough to put my thoughts where they should not be.
The same apply for me in respect of cues. I need to feel comfortable that the cue is "right" and a streaked
ebony cue was for me annoying (when I received it) and I had to ship it back to the manufacturer. I then received a new cue and it looked much better
- hence my brain was not focusing on minor things, just playing pool and enjoying the game.
If the cue makes you focus on the wrong things and feel it's not according to what you like, I would try to have it fixed or looked at.
We spend $ on these things because we want the correct feel including the looks of a cue - not just how it mechanically is built up and physical playability.
We pay for a package
However as mentioned by Chris, some times the wood makes funny stuff which is not the cue makers "mistake" or "bad work".
My cue was simply affected some way and had a fairly bright portion of the wood glowing up under the table lights.
I learned that a black ebony cue is not something I would buy again since it's natural variations could be large.
I can add pics of "natural variations" in ebony and a pic of how a cue have been "evened out" by using a felt pen to make points "even" in length if this is of interest.
