I think I've posted something similar to this before but I'll put it out there again.....I'm under the impression, maybe wrongly, that if your club has a speed of say.....2, and you use a ball that has a speed of 2, then added together you would have a combined speed rating of 4.
So if you then switched to a club that had a speed rating of 3 and used that with a ball with a speed rating of 1 ∴ giving a combined speed rating 4, would the meter speed be the same in both instances?
