I got fitted for irons with Recoil 110 graphite shafts and love them. Pretty firm and heavy enough although I do have backweights in them too. My elbows and bad wrist have really benefited. I've never really liked graphite shafts until I tried these.
I would also look at supplements that reduce inflammation to see if that helps. Curcumin (Turmeric), Ginger, Fish Oil, et al can help. I used to use Zyflamend and that helped a lot, but I think they may have changed the formula and it didn't seem as good. I use Drs Best Curcumin pretty much daily and it seems to keep my aches and pains away for the most part.
