We all have 'em. What are some equipment related things you read/hear here on the forum or elsewhere that most people agree with and you think are just plain wrong.
I'll go first:
1) If your misses aren't reasonably consistent (no tendency left/right or fat/thin) and you struggle to find the sweet spot more than a few times a round, getting fit is a waste of time, just get something off the rack.
2) We'd all be better off if we stopped reading this site, found a set that worked, and never changed until the grooves were gone or the faces caved in.
