I spoke for a short time with Billy Incardona one day in Dallas about this very subject.AS I recall he was playing a smaller shaft diameter,around 12mm or possibly less,it seems that Efryn and many Filipino players are doing the same.
I asked Billy,who knew my game fairly well,if it would benefit my game,since I am not a top player or even a good b or c shooter if it would actually hurt my play since my fundamental ball striking was inconsistent,
The question I asked was "would i actually play worse because my inconsistencies would be magnified more than the potential benefits achieved?"
Billy told me that he thought that the risk of playing the thin shaft would out weigh any gains that I might gain . He suggested that I stick with thicker shafts.
This is consistent with my own observations,I have never been able to play with pro taper shafts nearly as well as I do with thick taper,billiard or european tapered cues.
I currently am playing with a Schon,I have several shafts,all with various tapers and thicknesses to experiment with and the results are not clear or final,but the Kikel shaft with a 13.25 shaft is much more accurate and consistent,particularly on long long banks.
I play the best in the short 5/8 of the table and cut balls thin best with the 12,7 shaft and find that I draw the ball with more ease and power than any other shaft . This is the smallest shaft I currently have.
I am looking forward to getting my original Deano back which is about 12.5 at the tip but gets thick quick ,so I can continue the experiment.
My expectation is that if the taper is strong and the shaft stiff enough that the smaller mm will be helpful with minimum negatives associated with the thin shaft
At any rate John Nemic is making me a handful of shafts so i can actually test better this for myself
I am aware that some jerk is going to say that if I would take the time,practice and get instruction that I could play with anything. "a good player can play with anything"
While they have some obvious truth ,they are ignorant of other factors which are also factors which are the subject of the present discussion as i understand it

I would be interested in personal helpful comments on my PM if anyone could offer insight
