I got some Tribosys 3203 half a year ago to make some Ergo Clears with 65g springs.
I used 3203 for the stem and the switch housing, and Krytox VPF 1514 for the springs. The end result was very nice, and significantly smoother and better sounding that stock unlubed Cherry MX Clears.
I only have good things to say about these lubricants. Switchmod is a great and reputable vendor, and his owner — Krelbit — is a great guy!
I might get some 3204 this time, for my Topre boards. :)
