I had a prime m 12.0 and it had a lot of vibration in it on occasion. I would still rate it as 4th best of the 7 different brands I tried. However it was just the shaft on a different companies butt. You guys seem to be sold on the whole CF cue combo. I would like to try one this time without buying 1st. That's if I get to play at all again.
I had another brand carbon fiber shaft for one of my other wood cues and it didn't play like the Becue with the carbon fiber butt.
It sometimes made a "pingy" sound and it didn't have the same feel as the Becue.
I traded that shaft for a cue.
