Depending on size, taper, ferrule, etc. some maple shafts deflect less than others. That being said every CF shaft i've test-hit (about seven types) has deflected less(sometimes a lot) than any solid shaft i've had on hand. Some of those were fairly small with short, light ferrules and the cf still deflected less. The 12.9Revo deflected WAY less than just about any cue i'd ever used.Hi, Dave.
You said the Predator Revo shaft creates much less CB deflection than a typical solid maple shaft, but that has not been my experience in the one or two Revo shafts I have tested. I have another Revo shaft that I will test later today. If possible, I will post a video with the result.
Also, I enjoyed the video you earlier posted and I agree with all those things you listed as being the true advantages of carbon fiber shafts.
