Here is my 55g HHKB Type-S:
Sorry Vesper but I'm not a big fan of the 55g so far. Way too mushy for me compared to 45g Novatouch. I barely don't hear the thock sound on it. The space bar is rattling I'll add some thick grease so it gets really quiet. I feel it is a bit too heavy for me as on a daily basis. I'll give it some time and I'll see how it goes.
Heyo!
No need to be sorry
My HHKB currently is sporting 45g domes for alphas and 55g for mods
Everything seems to feel slightly stiffer in the HHKB compared to the Realforce. Might have to do with the profile/angle, or the lack of plate. 55g may be too a lil' too stiff for alphas in the HHKB for me too
55g is super snappy in the HHKB and really fun, more so than the Realforce, but I think it was designed for a plate.
I believe (I have been told by multiple sources) the mushy-ness is a result of the Type-S plungers being the standard Black plungers with padding but without reduced thickness of the plunger base to compensate for the pad. This results in the dome being already somewhat depressed, and reducing the maximum tactile feedback of the dome (making it feel more linear than tactile). The same thing follows for Type-S with 45g. Many people have said the Type-S feels lighter/less stiff than stock HHKB. The Realforce Silent Purple plungers have a thinner plunger base (longer stem) so that the base thickness + padding is the same thickness as a stock Black plunger. Also, the Realforce Purple plunger base is a round shape, while the Black plungers have more of a rounded square base.
You barely hearing the thock though is the padding in the Type-S, not the 55g domes.
Lubing will help with the spacebar rattling, but from my experience, it has more to do with the stabilizers not being snug in the stem hole. My remedy was using tape to fill that up. Let me know if lubing doesn't help you.
