The Harp is an overstable Westside approach disc rated 4/3/0/3, filed as a putter but used mostly for upshots. It flies straight and then hooks firmly, which suits windy approaches, forehand upshots and shots that need to finish left for a right-hand backhand. Players who want a straight putter that holds a turnover line should look elsewhere. Westside says it is built to hold up in wind, that strong players can carry it as their one approach disc, and that for slower arms it is very overstable. On Disc Golf Course Review, one player described a flat, comfortable disc with a small bead, and another questioned why a disc with these numbers is called a putter. The PDGA approved the Harp on 28 October 2013 (13-67), and Westside's Finnish site recorded the BT Soft launch on 1 March 2014. Its Finnish name is Kannel, and the stamp art is by Arto Hoffrén (2013). Colin Bryant has a Team Series run. On our comparison table its nearest matches are the RPM Discs Kea and the Discraft Kratos.

The Westside Harp is one of the most-reviewed discs we track.

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.

    I don't know why, but my harp has no fade and it's really annoying (VIP Moonshine plastic)
