So I recently got my PBT spacebars in the mail, and I am really happy with the spacebar on my HHKB. The ABS spacebar sound and feel was always my least favourite part of the HHKB2, and swapping it out for a PBT spacebar makes it near perfect. The deeper thock, no more squeekiness, no more pings... So good.
BUT, for some reason, I really dislike the sound/feel of the PBT spacebar on my RF87U. The spacebar sounds REALLY loud, clangy, and out of place compared to the other keys. It bothers me so much that I switched back to using the stock spacebar on this keyboard.
Has anybody had a similar experience? I'm thinking that it might be due to the plastic plate vs metal plate mount.
