I went to the Fitting Center at MCC, although I'm not a member there, the head pro has been my and my son's coach for nearly 10 years. As I've mentioned in other threads, I was fit for a TS4 a few years ago at another fitter, not associated with Titleist. The TSR4 worked briefly, but I always struggled with it and to get any kind of consistent performance.
Told Brandon my issues, my miss, and he wouldn't tell me which head I was testing at first from the very first strike - Holy Cow! - launch, flight, feel - what have I been missing all these years? Even my misses were still very playable rather than miserable duck hooks that caused instant double bogeys. I estimate 4-5 lost strokes per round just because of my poor driving. This is literally game changing. Tested two more heads, each was good, but not as good as the first.
Then we started fine tuning shafts, weight, flex, moving the weight in the head around. Ultimately going with the Mitsubishi Tensei Black in 60g, stiff, with a GT1 head, 10*, in C4 hosel position. Did it magically gain me oodles of ball speed? Yes and no. What it gives me is consistency - finding the center of the face more and optimizing the performance I'm capable of. Rather than heel and toe (or worse strikes) and maybe eeking out a 220 drive which I can hit my 3 wood farther (and 99% of the time, tee off with a 3w), I'm where I should be for my swing speed and more importantly in the fairway, or at the worst very playable.
Thank you, Brandon and Titleist. Can't wait to get it delivered and onto to the golf course if the weather will ever improve.
