I think Plum is dropping the ball a little bit by not having anything other than 35g variants easily found for purchase here in the US. If there was a 45g or preferably a 55g version of this in this I'd be in for one in a heartbeat. Not only that but I'd imagine they be pretty popular within the community being a more affordable electro capacitive switch based board than Topre.
wolfinFrom my understanding based on reading keyboard forums in Korea and Japan, they seem to prefer the lighter actuation weight more than 55g variant. I don't have any numbers to back this observation though.
