Bella putter head (Bella-Fit Fitting System)

The 2012 Bella putter head is the centerpiece of Yes! Golf's Bella-Fit Fitting System, and per thegolfwire.com's reporting, its defining idea is consolidation: a single Bella head meant to serve face-balanced, moderate toe hang, and pronounced toe hang golfers alike, rather than requiring separate models for each stroke type. That same reporting describes an adjustable hosel for lie angle and telescoping shaft options that stretch coverage from standard length (26 inches to 37 inches) through mid and belly lengths (36 inches to 47 inches) up to long putters (46 inches to 52 inches), which suggests a system built around fitting flexibility across both stroke style and length rather than a single fixed spec.

On the face, thegolfwire.com reports a TPU65D insert set into a precision milled slot, paired with what the outlet calls True Square Alignment and C-Groove Technology, the latter said to help the ball begin pure roll up to 21.5% sooner. The same source also credits the design with improving off-center hit accuracy by up to 40%. These are editorial figures from thegolfwire.com, not maker-confirmed specifications, and should be read as one publication's account of the release rather than an established record.

Within the Bella-Fit line, this 2012 head reads as the fitting hub, the one part of the system reporting positions as adaptable enough to answer multiple stroke profiles and length needs at once, with the insert and groove work layered on as the performance claims attached to that single head.
