I visited the Titleist National Fitting (Scotland) at Craigielaw yesterday (14th October).
I would firstly like to comment on the fitter Graeme Noblett, he provided me with great information and explanations why I should be choosing particular clubs and specs.
I am currently using AP1 716 (4-PW) XP90 S and he fitted me for T200 (5-PW) AMT Red R300.
I had a small gapping issue at the top end of my bag, and he changed the setting on my TS hybrid 19 degree from A1 to B2 setting and this increased my distance, height and landing angle.
Lastly, if everyone has any doubts about booking a fitting at a fitting centre, I would highly recommend doing it, although it comes a cost, the experience is well worth.
