Treated myself to a set of 716 Ap2 irons and 915 woods April of last year, what a difference a year and 3 months has made. After my fitting my handicap started dropping immediately, 9.4 at the time of fitting. I then added Vokey wedges and a Cameron putter ( both fitted also) now 15 months on and I'm now playing off 1.2.
I absolutely love Titleist and strongly recommend anyone to get a fitting, the right clubs for your swing and a bit of practice and your handicap will plummet!!!
