Personally, I would buy all new clubs. I just reshafted a couple of sets of clubs when I got fitted for shafts and it was probably $400 per set for steelfibers. If I had not recently bought two sets of concepts (the reshafted clubs), I would have bought new clubs altogether.

I'd say time to upgrade. If you figure $40-50 a club to re-shaft, $100 a club for a top line used set, and $175-200 for a new premium iron, you're in the ball park.

They were a great club back in the 90's. Won a set for winning my flight and played with them for a few years. Again, they were great in their time. The technology has changed. I play with a buddy who still plays them and he shoots in the very low 70's. Guess it proves it is the indian, not the arrow. Being you do not play often enough to warrant a new set, you might look into other newer Titleist forgiving clubs that might be just as cheap as replacing the shafts. If you want a forgiving club you might check out the T300 which is a very good forgiving club. Replacing your shafts could run you $400+ based on $50 times eight clubs, minimum. Would advise to use caution when looking on eBay. A lot of fakes out there. Here is one site that I would trust if you are interested in doing some research. It is a Titleist account in my area. www.bogiesrus.com/.../used-iron-sets

If it were me, I would go to a Titleist fitting. You will get to try the latest clubs to determine if they are right for you. You will also get to experience the different shafts and how they interact with your swing. If you decide to keep your old set, you will have a pretty good idea of a shaft replacement. If you go that route I recommend having a qualified club builder do the swap so they can get the swing weight, lengths, etc. dialed in for you.

In September I bought the T350 Irons. They are the best Irons that I have ever hit. I have played Titleist irons for many years. So easy to get the ball into the air. High ball flight and soft landing especially when I play the Pro V I and the AVX.. Great work Titleist.

Buy a newer set of irons. For each shaft you replace, you're looking at $80 minimum. You can buy a good used set of irons for under $300.

You are probably better off finding new clubs on eBay if you can’t justify new clubs. Switching shafts at a store willl cost you at least $25 plus the cost of shaft which is another 25-75. Used clubs. On eBay
our local marketplace is going to be similar cost.

Interesting scenario. Those clubs are very old, but obviously you like them. I cant imagine the problem with your shafts wont continue to get worse as they get older. If you dont want to get new clubs, which in this day an age you can always find a great deal on used clubs, even of the newest generations, might be worth at least getting your iron updated to a new set of shafts and grips. Any golf store or pro shop could handle this.

New shafts will likely make the clubs different and you won't like them any more. Best get fitted for new clubs instead. Then you won't be disappointed.

You can pick up a good set of older irons for less than it would cost you to buy new shafts, not including installation.
I switch between 2 sets of CB irons that I paid about $250 for each. One's 12 years old and the other is 10 years old. They don't have the all the fancy tech, but I don't play irons with all the fancy tech anyway.

Look into getting some 712 or 714 CB/MB irons and they should run you around $250. (More forgiving, the AP2) (AP1 most forgiving, but not as much as other brands)

As others have said, it is often cheaper to buy newer clubs, especially if you can get a deal on a newer used set. If you decide to reshaft, make sure you go to someone with experience.
