I have a set of Mizuno JPX 919 irons with Pro X Catalyst 60 shafts which were provided by a nationally well know club fitting company. They were fine but not as accurate as I thought they should be. I just thought it might be my age so I've been living with them for the last few years. Well I lost my 7 iron and it was never turned in and to replace it with the same fitting company was $300. I said no to myself and found one on eBay with a Dynamic Gold 105 r300 shaft. My first swing felt great and hit it stone dead. Ordered a set of shafts from The Golf Club Trader and now I am a very happy golfer.
Worked great
