I had a fitting on the 9th of October (T200 irons and 2 Vokeys) and placed the order on the 11th through my club.
The Titleist fitter said 5-6 weeks for delivery - i.e 16th-23rd of October, and that Titleist were picking up a lot orders due to other manufacturers having long lead times.
I have just chased and been told that the iron heads are due into Titleist on the 25th of October and with the backlog there is an estimated 27 working days build time (which is Nov 30th).
Expect mid-December as the build time may get longer. That will be 14 weeks if they come in mid-December. TBF I was told that the build time may be shorter but I can't see that happening to be honest.
For me the Titleist fitters should have more up to date information on delivery times, so as to be honest with managing expectations. 5-6 weeks with a 27 days build time means Titleist would have had to have had the heads in stock, which they polainly didn't.
Anyway, 68 hours until my tee-off time on Friday.
