What’s your bag setup and what do you use the 18.5 to do?
If you are hitting everything else better but can’t hit that, I’d maybe replace it instead of learning to hit it… probably just a setup issue, but I’d worry fixing it will impact the rest of your bag!
Plenty of great used options out there, just need to find the right fit for you.
Are you better with fairway woods now? I’d just find something that works!
