No. 1/2 degree of torsional stiffness will not be noticeable by a vast majority of players. Anyone that does notice anything will only notice that the slightly higher torque will feel very slightly softer, but this player will have to have Tiger Woods sense of feel. No affect on performance or ball flight. Also understand that every shaft manufacturer measures torsional stiffness differently and the torque readings you see are the readings on the raw, uncut shafts. Once they are cut from the tip (if necessary) and installed in the hosel, the actual torsional stiffness changes (goes down a little when installed). I consider the readings that are published a general way you can compare the torsional stiffness as it will apply to the feel of the shaft. In other words when comparing two shafts of similar weights, bend and trajectory profiles, an R flex with a 3.5 torque vs another R flex with a 4.0 torque might feel slightly stiffer. In my experience the only time torque might have an affect on performance is if a 110+ mph player with an aggressive swing hits a shaft with 10+ degrees of torque vs a shaft with 3.5 degrees of torque. there would be some inconsistency in flight. Of course he would notice the feel difference too. Some players with any sense of feel might notice feel differences in torque variations as little as 1 degree, but for most the difference might need to be 2 degrees or more. In short, it takes a big difference and real mismatch of torsional stiffness to a players strength for there to be noticeable ball flight differences. Feel differences, on the other hand, might be noticed with smaller variations in torque (but not 1/2 degree).
