After over three straight hours of very firm shots to a rail with a 1.5 tip-width of side spin, and using a training ball for a consistent hit, here are my unscientific conclusions from the deflection testing I promised here the other day. I gave each shaft a number designation so I could better show the degree of differences in the results. I used the same bridge length for each shaft and the cue ball was four feet from the object ball. I was constantly rotating the shafts for more accurate results
By the way, even though I really like the 11.8 Revo, I'm still in the market to replace it, so if anyone feels they have a CF shaft with a lower deflection, I'd like to hear from you. I'm not concerned about feel; just performance. There's a store nearby that allows testing of their cues. Thanks!
[To the original poster of this thread, mrpiper, the Viking Siege feels like a 12.5 Cuetec Cynergy in that it has the same soft hit when compared to the Revo's, but I would say a bit less deflection than the Cynergy]
Predator Revo 11.8mm... 5
Predator Revo 12.4... 4.5
Predator Z3 11.8... 4.25
Viking Siege 12.5... 4
Player's HXT 12.75... 3.5
Player's regular wood shaft (non-low deflection)... 2.5
