BRAINSTORM HAPPY (BLADE)
CATEGORY: Blade Putters
WE TESTED: 34", 35" lengths
KEY TECHNOLOGIES: Removable faceplates tweak loft (1°, 3.5°, or 6°), while interchangeable 3-, 6-, and 15-gram plugs alter headweight.
DISTANCE CONTROL: The Happy's strongest attribute -- once testers dial in their settings and get comfortable with the overall look, controlling pace and distance is a snap; predictable speeds provide confidence on testy downhillers.
FEEL: Testers like the fact that you can customize feel -- and performance -- by changing head weight, amount of offset (zero, half-shaft and full-shaft), or lie angle (68°, 71°, 74°); oval-shaped grip grabs your attention; center strikes are soft, while off-center contact produces a slightly less resonant pitch.
LOOK: Green, blue and yellow color scheme gives it a cheery, light-hearted look; at address, the broad flange seems like a midsize mallet; contrasting alignment lines help with setup.
Not everyone is happy with the overall look; all the adjustability features can be overwhelming; oval grip doesn't suit all the testers.
BOTTOM LINE: A tinkerer's dream, with loads of adjustability options to make it work for just about anyone on any course. A new heel-shafted model ($350; not tested) also has removable alignment aids.
