i have owned five or six Predator cues and almost all of the shafts have had some roll out. i bought a brand new 30" uni-lok from a reputable, high volume dealer and it had roll out. i have read and been told that 314's are notoreous for roll out. i have an old 314 now that i tryed to straighten on a jig i made to no avail. i have it hanging on a cue holder with the butt on it for weight to see if this works. the roll out is only a credit card between 8" and 18" from the tip. is there anything else i can try? thanks for any input you can give.
