I have a Titleist TS3 @ 13.5 degrees with a stock HZRDUS Smoke shaft that I would describe as mercurial.
It can go high but prefers to deliver a low, cruise missile-style shot that carries 240 yards and rolls out another 10.
It was my go-to club into the wind at Cabot and I have reached so many par fives with it, yet there are some days where I have just cold topped the ball in the most hackerish way.
It's happened enough times now that I just laugh when it happens. It's almost like the club is disinterested if the degree of difficulty of the shot is low.
The good shots are plentiful enough to keep it in the bag but I can't help but feel the club has it out for me some days.
One thing I did realize about it is I cannot swing easy with it. Something about the shaft requires a full effort or else it just doesn't work right.
