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 Firm plastic is the most stiff/firm OG plastic. While firm, it is not brick hard and still has excellent grip.
