Where it wins
- Looks88

Watch
Rated highest for looks and distance; its softest dimension is workability.
You putt with a strong arc, want a highly forgiving, great-looking mid-mallet with class-leading dispersion control and the soft White Hot feel.
You putt with a straight stroke (the face-balanced Rossie DB), or you want a compact blade.
Pros
- A highly forgiving mid-mallet - much less dispersion, especially off-centre
- Found shots very close to the hole across longer-length putts
- One of the best-looking mallet putters available
- A strong-arc slant neck plus adjustable front weights
Cons
- A strong 46-degree toe hang - straight putters want the face-balanced DB
- A larger mid-mallet than the original Rossie
- A 2024 design now superseded by the 2026 Ai-Dual line
By dimension
Forgiveness
ExcellentExceptional - the modern Rossie is a highly forgiving mid-mallet, much bigger than Odyssey's original and one of the best mallet putters available, with much less dispersion especially when struck off-centre, helped by the large, perimeter-weighted head and Ai-One insert. Among the more forgiving mallets.
Distance
ExcellentA standout - testers found shots very close to the hole across a variety of longer-length putts, the Ai-One insert giving consistent ball speed. Among the better putters for distance control.
Workability
StrongA strong-arc mid-mallet - the Rossie S has a short slant neck with strong toe hang of 46 degrees, suited to a strong arc, with a double-bend face-balanced option separately, the slant neck improving operability for arc players. Good arc-fit - an unusually arc-friendly mid-mallet.
Feel
ExcellentSoft and responsive - the Ai-One insert keeps the iconic White Hot feel, an aluminium backer with a White Hot urethane striking surface, a soft, satisfying strike. Strong feel - the iconic White Hot softness.
Sound
ExcellentA soft, muted note - the White Hot urethane insert gives a soft, muted note at impact, a clean, dampened acoustic. A clean, muted putter sound.
Looks at address
ExcellentA great-looking mallet - the modern Rossie remains a really good-looking putter, one of the best-looking mallets that frames the ball confidently, a clean, premium shape. Among the cleaner, best-looking mid-mallets.
