The Ruru is RPM's slow putter rated 2/3/0/1. It suits straight putting and approaches with a mild finish, especially where a hard fading hook would miss the intended route. A player chooses much of the line at release rather than relying on strong overstability to correct it. RPM places the Ruru in its putt-and-approach range and names it after the morepork owl. The slow pace helps frame the role: controlled short-game travel, with enough fade to finish gently toward the fading side. The PDGA approved Ruru (PA2) on 29 December 2016.

Try Discs adds up reviews from six disc golf stores, so you see what players think across stores, not just at one shop. Reviews are great for spotting proven, popular discs. Take the details with a grain of salt, though: runs, plastics and skill level all change how a disc flies, so your experience may vary.
