Performance index
Six researched ratings, lower (blue) through to elite (gold).
Where it wins
- Looks86
- Feel84
- Sound84
Watch
Rated highest for looks and feel; its softest dimension is forgiveness.
You swing hard, spin the ball too much, and strike it from the middle — and you want the lowest-flighting Titleist of its day.
Swing moderately or want forgiveness? The TSi2 or TSi3 will give you more speed and an easier launch.
Pros
- The lowest-spinning driver in the TSi line — a penetrating, running flight for a fast, high-spin swing
- A genuinely workable compact head that shapes the ball both ways
- A substantial, solid feel and a punchy sound off the middle
Cons
- It punishes a mishit more than any other TSi — the compact 430cc head needs a repeatable, centred strike
- Built for a fast swing alone — below roughly 110mph, the TSi2 or TSi3 will do more for you
- No spin or bias weighting beyond the hosel — less adjustable than the TSR4 that followed
By dimension
Forgiveness
FairThe tightest miss-tolerance of the TSi family — a compact, forward-weighted 430cc head that only rewards a centred strike.
Distance
StrongThe lowest-spinning TSi — a forward weight kills spin and dynamic loft, turning a fast swing into piercing, running yardage.
Workability
StrongThe most workable TSi by Titleist's own reckoning — the compact head shapes draws and fades for a skilled striker.
Feel
ExcellentA substantial, solid strike — a dense, powerful thump off the middle that rewards a flush hit.
Sound
ExcellentA firm, muscular pop at impact — punchier than the old TS heads, and it sharpens on an off-centre hit.
Looks at address
ExcellentA compact, clean pear shape in a dark finish — great behind the ball, if it sits a touch shut for some.
