A lovely semantic argument which has become personal. Jon, you suggest that you are rolling to allow you to maintain an appropriate speed with a higher cut. One can call that rolling to get a higher cut by assuming that the speed is a given or if one assumes that the height of the cut is the given, then one would be rolling to increase speed. Either way, the club is seeking a means to achieve its perceived ideal combination of speed, smoothness and height of cut. One can argue about the ideal formula, e.g. what is an ideal speed or what is a healthy height, but it does not appear that there is any significant dispute about the tools or their effectiveness.
