Doon (Sigma G)

The Doon that shipped as part of the 2017 Sigma G line was a silver mallet built around a counterbalanced setup, according to pluggedingolf.com. Ping paired the head with what mygolfway.com and tgw.com both describe as a PING CB60 grip, and pluggedingolf.com puts the specific counterbalance package at a 130 gram, 17 inch grip. TGW.com's description of the release calls it plainly a counterbalanced model, and mygolfway.com flagged it at the time as a new addition to the lineup.

On price, the record shows a split by market: pluggedingolf.com lists $220 USD for the counterbalanced Doon, while mygolfway.com puts it at 245 EUR.

Reviewers who spent time with the Sigma G Doon came away with a consistent impression of stability, though not uniform enthusiasm for the feel. Pluggedingolf.com wrote that "though the head feels incredibly stable, I was still able to sense mishits in my hands," and elsewhere described the feedback as producing a sound "that's slightly metallic," a tone the same review says fades on mishits while staying consistent across different golf balls. That same source also placed the feel as firmer than the Anser or Piper within Ping's own catalog, a useful marker for anyone comparing the Doon against its stablemates rather than judging it in isolation. Community opinion elsewhere echoes the stability read, praising the counterbalanced setup for a steady, planted feel through the stroke.
