Where it wins
- Looks86
- Feel84
- Sound83
Watch
Rated highest for looks and feel; its softest dimension is forgiveness.
You swing 110+ mph, spin the ball too much, and want the lowest-spinning, most distance-maximizing Titleist - a compact 430cc players' head for the most accurate ball-strikers.
You swing under ~110 mph, need forgiveness or easy launch (the TSi2), or want the workable, CG-track TSi3.
Pros
- One of the best low-spin drivers of 2021 - the lowest, most forward CG in the TSi family, spinning around 1,964 rpm in testing
- About 250 rpm less spin than the TSi3 for maximum distance on solid strikes
- A compact 430cc classic pear shape for control and workability
- SureFit hosel plus headweight adjustability for a precise fit
Cons
- The least forgiving driver in the TSi family - relatively unforgiving on mishits
- Built for 110+ mph swings - slower players are better with the TSi2 or TSi3
- No CG track - headweight adjustment only, unlike the TSi3
By dimension
Forgiveness
FairThe least forgiving TSi - the forward CG and low-spin design make it relatively unforgiving on mishits, the least forgiving option in the TSi family, despite being more forgiving than the old TS4, the compact 430cc head demanding the most accurate swings. A head for consistent centre-strikers only.
Distance
StrongUltra-low-spin distance - launch-monitor testing recorded 145.8 mph average ball speed (some over 150) at just 1,964 rpm for 246 yards of carry, the lowest, most-forward CG in the family giving maximum distance on solid strikes. Elite distance for a fast swing that spins it down.
Workability
SolidCompact and shapeable - the compact pear-shaped players' profile is designed to increase control and workability, the small, low-spin head rewarding shot-shapers. Workable, more about flighting and spin than big horizontal curves.
Feel
ExcellentSolid and improved - the compact TSi4 has improved sound and feel over the old TS4, the ATI 425 face giving a solid, premium strike. A clean, quality sensation.
Sound
ExcellentCrisp and improved - an improved acoustic over the TS4, a confident, controlled note. Clean for a compact head.
Looks at address
ExcellentCompact and tour - a classic, small pear-shaped players' profile, a compact, confidence-inspiring look at address. Sharp for the better player.
