Wanted to get some input on cues with a roll. Is there such a thing as a perfectly straight cue?
I believe there can be. A lot of manufacturers take time to dry their wood, and lathe them to be as straight as possible. Perfect, I guess, is subjective like qbilder said. But short answer is yes.
How much roll is too much?
My answer was essentially going to be this, almost verbatim:
IMO, if you roll the cue across the table & it doesn't flop or wobble, it's just fine. If you sight down it & it looks straight, it's plenty straight enough to play with. If you have to put your face on the cloth to watch for variance in light under the shaft as the cue rolls, you're being a bit nit picky.
How do you test a cue to see how straight it is? (Best Way).
As qbilder stated, I sight it. I roll it while doing so. I also check on a table for wobble.
How much will roll affect the playability of the cue?
Whenever I played with a stick that wasn't straight, I always found myself compensating for it. I use to have to adjust on the fly, and figure out which way I wanted the curve to face. It's a pain trying to determine how a crooked stick is going to hit a cue ball. Adjusting to deflection on a stick with which you are unaccustomed can be bad enough. To have to factor this in as well? It's tough.
If you bought a new cue and it had a roll, any amount of roll, would you send it back?
Absolutely. Without a doubt. That's why I bought my stick straight from the certified dealer. I didn't want a middle man. No way am I going to have to fight and dicker with some online store about how the cue isn't straight, and if I had abused it or not. No ifs, ands, or wherefores. I picked mine up in person. Dealt with the issues I had right then and there, not that I had any.
On a side note, I bought my cue new. The reason I went straight to the dealer is that if something goes wrong with the stick, I have a warranty on it. Again, it just takes out the middle man. When making that kind of investment, I want to insure that it is as well protected as it can be.
