I tried the cherry silent black stem in the Rosélios housing and it is smooth and quiet but I actually like the Silent Alpacas more.
I also tried the Silent Alpaca stem in the Gateron Ink housing and it was good. I’m not sure if I preferred that or just switch filmed Silent Alpacas.
One interesting thing, and I need to check this further, but I believe the keycap is actually sitting about a millimetre lower on the alpacas than all the rest of the switches I own.
