i never said all.i said some or a little,i really can't remember which.i have played with Maple shafts that have deflection properties similar to Predator and i have played with modified Predators that had similar deflection of a factory shaft,and i have played with some modded Preds that were obvioulsy higher in deflection.i think part of the problem is thinking you can tell the difference of .10" in your mind on a 4' shot for example.if you and Dave thibk you can discern that minute diffference then that might be part of the problem.it just isn't possible.even if you or any human,there are way too many variables for it to be viable.i don't think it is all as cut and dry as you think.do you believe that there are custom shafts out there with similar deflection characteristics as a Pred?they do exist i have seen them.i think if you had some cuemakers that were trying to make very low deflection shafts make shafts and compare them to Preds you would be surprised at the results.
