Hi! Curious is this *the* Mike Davis, pro player? Anyway I have experienced a similar thing. I've tried the new Meucci Pro shaft. One I loved, two I only liked. Those two seemed to have more deflection than the other one. Since wood is an organic substance, I think it is susceptible to variations of all kinds. However, I think the radial lamination process helps to "standardize" the differences. The Meucci shaft isn't laminated, so the differences there are more understandable. For a Predator shaft, I really believe the biggest differences in deflection would be due to the tip. In particular, how tall the tip is and to a lesser extent what type. I very big tip essentially adds some mass to the end of the shaft, which directly increases deflection. It seems that the least deflection comes with a fairly short tip. I have read that a dime radius gives slightly lower deflection than a nickel or flatter shape.
