Is there any reason as a high handcap golfer to replace my irons Ping I3+

I am in the same boat and I’ve been thinking about getting fitted for years. I play with the only set of clubs I’ve ever owned, which are 25 years old.
I shoot in the 90s and realize that new clubs won’t all of a sudden put me in the 70s. But I finally decided to get fitted and went last week for a full bag session and had a great time.
The advances in technology for heads, shaft, and everything in between can’t be understated. I can’t describe how much more flush the shots felt with the newer clubs. The difference in distance alone is prob worth 2-3 shots a round. The forgiveness in these newer clubs is amazing.

I put my order in today. Can’t wait for them to come in.

maybe a touch of distance and forgiveness would come with new clubs.

But if you like the irons, just get fitted to some new shafts. No reason to ditch them if you like them.

You would probably get a good bit of help from a newer set. Not much changes in golf iron tech in under a decade but 20 years is a long time. Just my opinion.

I see a few people saying no, I say yes. 20 years is old for clubs. Without changing anything in your swing, you will get a little more distance and a little more forgiveness. Plus they will last you another 20 years.
Guessing your wedges are 20+ too. Short game would see a little improvement too.
