I told my fitting story for my driver above but can’t reiterate the benefits enough.
Played with someone this past weekend who I was equal with off the tee, he got new driver and was ahead of me, i got fit for a new driver and now I’m wayyy past him.
Go. Get. Fit.
Irons if you know loft/lie/length you can probably get 80% there on trying out clubs on your own. Driver there is NO WAY you can do it on your own.
