Titleist TSi2 vs Titleist GT2
You play the Titleist TSi2. Is the Titleist GT2 worth the money? Published specs side by side and a verdict from rules we wrote down before we looked.
Verdict
Upgrade only if…
Upgrade only if one of these is you:
- …you need a loft your driver doesn't come in: the Titleist GT2 is also sold in 8°. Source
One of the two brands doesn't publish: published MOI, USGA conforming list. We leave those out of the verdict instead of guessing.
We don't have verified prices for this pair yet, so the strongest verdict we give is “Upgrade only if…”.

These are the brand's words, summarised. We have not tested them, and they never change a verdict.
Our take Our assessment (based on published specs)
Four years and two model cycles separate these, and the published specs still overlap almost completely: 460 cc, 58.5° lie, SureFit hosel, a fitter-adjustable weight, and lofts that match from 9° up.
The GT2 adds an 8° head. That is the only fact-based reason on this page. If you play the TSi2 in 9°, tee it low and fight spin, the 8° is worth a fitting appointment. If you don't, it is irrelevant to you.
Two things we can't tell you: Titleist never published a US launch price for the TSi2 that we could verify (the GT2 was $649), and the TSi2 page doesn't state its standard length or list left-handed availability, so those sit as not available rather than as a guess.
Titleist's claims cover the rest — an ATI 425 face for speed on the TSi2, "fast yet forgiving" for the GT2 — and neither carries a number we can compare.
Our read: unless you want that 8° head, keep the TSi2 and spend the money on a fitting or on the ball you play.
