Hi Dave,  If your irons or wedges are not holding the green with a ball like a ProV1 or ProV1x, (and they used to hold), your grooves have probably lived a long life, but it may be time to put them to rest.  You can also visually inspect the faces to check on wear. 

In the pre 2010 era, players would regroove wedges, but post 2010 groove rule, it would take very sophisticated machinery to have your irons/wedges regrooved and maintain conformity to the 2010 groove rule.  It sounds like your equipment has had a good long life, but with the new launch of the 716 irons, it may be time to see how technology has improved the feel and performance of new irons!

Thank you Cathi,  guess Santa will be getting a letter here shortly.

Before I buy new wedges, any tips on how to give it a try myself? I'm setting aside some $ to eventually purchase new, but I'd sure like to learn how to proceed. I really don't have much to lose. Thanks.

any suggestions would be welcome.

I went to a demo day that happened to be scheduled not too far from me.  It wasn't as good as a full fitting, but I at least was able to try out a variety of wedges in different colors, bounce, and lofts.  I was surprised at the results and ended up getting different wedges than I had originally anticipated.
