Has anyone actually compared the weight of an open gear Grover vs a Closed gear Grover mini Rotomatic? I'd be willing to bet they are very close to the same weight all things being equal like tuning knobs. (metal vs plastic)
That prompted me to do a quick research on Kamaka, Koaloha, Koolau and the Kanilea standard tenor/soprano ukes. The Kamaka, Koaloha and Koolau tenors use sealed geared tuner for their standard tenor ukes. Kanilea uses open geared tuner for their tenor uke. Kanilea uses open geared tuner for their soprano while the other three Ks use friction tuners.That said, my KOaloha tenor has them, as does my Bruko baritone. Go figure.
