This belly putter was inspired by Rife's tour model, the Cayman Brac. Rife has modi?ed the back to bring its overall weight up to 400g. The Blade goose neck makes it an ideal putter for those who arc their swing path. While, the PHENOM Z is an exaggerated version of the Phenom that highlights its slim top line. The back of this putter is geared to optically optimize parallel alignment.
