Hi. All the talk about “long” springs and 55g or 57g being the lower limit for Boba U4 seems to actually be about TX L springs. And these springs are only 16 mm long, so not very long.
So, did anybody try 22mm springs, such as the ones from mStone, inside Boba U4s?
I haven’t tried this brand out yet, but I tried swapping with springs from Outemu Silent Lemon (22mm, 50g bottom) and Outemu Silent Peach (22mm, 45g bottom) and found that both were actually usable. Just, to be honest, the 45g one seems to be a bit lacking when pressing the key slowly. Also I only use 1U and 1.25U keycaps (and added some lube, but it was already ok without doing so).
So does it work only because Outemu springs actually are heavier than their nominal weight? Or 22mm is after all the way to go and I should just go with it and order mStone 22m 50g springs? (or some other brand with equivalent specs).
