Well let me ask this then. Why is it that when I mapped my Ping G20's with full backspin 9i they had a carry of 119 yards every time I dinged it. The i500's have a variance of 2 yards on a ding. This is very low side to side wind, no elevation & no apparel abilities. Were some of the older retired clubs way more precise or something? I would think that the i500's should perform exactly like the G20's but they don't seem to.
