If i have to use sub hands for a build, i either use gen (with gen movement) or TC hour hand or Vietnam hour hand + HR minute hand + ETA 116610 seconds hand (which has a slightly longer tapered front; therefore, it is good for building certain periods of 1016).
IMO, Clark, Yuki, stock cartel, and Startime sub hands look nothing like gen. I don't understand the praise about them haha. I would say HR's sub hands is the better one, but far from perfect.
If you are dying for something quick, Rafflestime (not rafflesdial) sub hands look quite nice: they look like they have the right proportions and they are cut very nicely:
Rafflestime minute hand measures 12.5mm from centre to tip.
