I .am 69 years old and have a set of CB712 irons 3-9,PW. I have DG R300 shafts in them. I am thinking of putting TT XP95 shafts in them. I am losing distance because of age and i am wondering if a shaft that is 32 ounces lighter would give me the speed that might help with the loss of distance. I still hit the irons great and i dont want to jack the lofts up like all of the sets are today. Thoughts? Thanks. Don
