Inspired by the Golden Ratio, the Phi is a beadless putter that is slightly less stable than the Penrose. It features a semi-deep profile with a smooth, rounded geometry that is stable enough to handle headwinds and tackle long approach shots with unmatched glide. Those looking to test out a beadless option for putting or a versatile and dependable driving putter, look no further - the Phi is the new golden standard of putt and approach discs.
OG Medium plastic has a slightly firm feel. It is a bit more firm than the OG Base, but less firm than the OG Firm.
