GolfDaddy96: I want my meter speed to be the same for every club.
The answer is an Emphatic and resounding No (zero doubt). Unfortunately everyone else is mistaken.
Just as a very small example, my TM Wedges and Cleveland Wedges are both rated at 3.5 meter speed. I can tell you with 100% certainty that the Cleveland wedges have a significantly slower meter. The same holds true when you're playing tournaments with Set-of-the-week. The random putter might be listed as the same meter speed as your current/normal one but they are quite different.
The same holds true when playing with different types of balls, more specifically the lower rated ones such as WGT brands. My L95 Nike irons seem to be a pretty close match to my TM Wedges,but again, this isn't universally true across the board.
My suggestion, buy whatever you want and in time muscle memory will be your best friend. Don't don't go switching clubs/wedges/balls all the time. Purchase> into muscle memory> into better scoring.
