Typing on my first Cherry MX keyboard in 4 years... a recently acquired Duck Viper.
Lubed 68G Vintage Blacks are pretty damn heavy for my whimpy fingers (coming from 45g HHKB and 55g 87U).
But they feel oh so buttery smooth with tight tolerance.
I guess I won't need to try the 78g Zealios in future builds, 67g seems like the sweet spot for me (or the max).
Here is a photo with LEDs off to save you the ugly light bleed from the TA set, it is the only MX keyset I own at the moment.
