If I had to do it over again, I’d likely have gotten fit.
Even if your swing starts off total crap, your fitted clubs will pretty much work fine even if you gain like 10-15mph. It’s not that big a deal to get fit when you’re a noob then advance to not a noob with a decent swing.
A decent club fitter will take all that into account.
As for getting nice shiny clubs, if you like them, get them. Chances are you’ll be able to use them for years to come...
