Hi all ,just to my local fitting centre in St Helens and I have to say it's worth getting fitted before you buy any new clubs ,the difference between my clubs with my 710stiff s300 shafts in to my new 716 irons x100 kbs tour shafts ,I am hitting my clubs 10 years long on all clubs but even better news is that my miss hits to the left aren't as wide as before due to be fitting correctly with new shafts and I would strongly recommend that before you spend your money on some new titleist irons just try the fitting before hand to make sure you are getting the maximum out off your game..many thanks to Clarkes golf centre ,kind regards Kevin
