Oh contraire my friends lets not place the blame on the stroke. The shaft, taper, joint and type of wood have a lot more to do with it than the stroke. I am not saying that the stroke has nothing to do with because it does (some) but the action he is getting on this shot is more stick than stroke. At present time I use a Lucasi with a Uniloc the shaft has been modified several times and now has a 14 in pro taper at 11.60 dia., 1 1/4 length ferrule with an Elk Master tip. I have in my arsenal a Predator 314 and OB1 shaft and IMHO all are much to stiff to give me this kind of action. I have stroked many a cue ball top, buttom, left, right, inside and out and have never got the cue ball to behave like he does so I am not buying that stroke business.
