Guerin Rife IMO Putter Right 43 in
The Rife IMO putter features an all aluminum putter head with 85 percent of the total mass concentrated in the middle 40 percent from a front to rear direction. The sides are hollowed out underneath and only represent the remaining 15 percent of the heads mass. The USGA requires that a putter must be longer from a heel toe direction than from front to back. The IMO is right under this limitation measuring 4.75 inches wide and 4.60 inches deep.
