Titleist TSi3 Review

TSi3 is the players' model of the pair and the fitting story is the SureFit CG track, a channel across the rear of the sole carrying a weight that locks into five detented positions from draw to fade. Because the weight itself does not change, only its position, bias can be adjusted without altering swing weight, which is the detail that makes it useful in a fitting bay rather than a novelty.

The head shares the ATI 425 aerospace titanium face with the TSi2 but sits in a more compact profile with a more forward centre of gravity, so spin is lower and the flight flatter, at the cost of some forgiveness on the heel and toe. It looks slightly smaller and squarer at address. The SureFit hosel adds sixteen loft and lie settings on top. Lofts are 8, 9 and 10 degrees. Grades here are a provisional placeholder held flat at C until this head goes through a proper fitting and a full launch monitor block.
