I like to use yellow balls so I know which one is mine when playing a foursome!
My swing speed isn't high enough to use a 15* 3W off the fairway.
My fitter was genuinely surprised to see that I could hit a 16.5 fairway off the deck that was only a few yards less than driver off the tee!
They changed the lofts. My 7 iron is only 27 degrees loft!
