Ah, okay. I have heard of the OUTEMU Silent Gray, but never got around to getting them.*
In terms of silent light tactiles, there are more options today than in the past.
There’s Gateron Silent Brown [which sux - they’re not that quiet, and the feel is mushy].
More recently, there’s Kailh BOX Silent Brown. These are interesting. Use the V2 housing, I think. So they can be used with North-facing PCBs and lighting. They are a medium-tactile, like a scaled down Zilent V2. About 50-75% of a Zilent V2. They’re a little sharp and heavy for my liking. But you can put the stem in a BOX Cream linear housing to make “Cookies and Cream.” You can look them up.
The main thing I don’t like about BOX Silent Brown is the reduced travel. It feels like 3.2mm or less, and I prefer at least 3.6mm in MX switches.
So in terms of full-travel, there’s Aliaz. Discounted rn at Flashquark, 49 cents. They are like Gateron Silent Brown, but may be built to a slightly higher spec [smoother?]. I find that you only need to lube stems on these switches. The stock springs are terrible, undermine the switch with their ping and their crunch. But with replacement TX springs, they are good. I like lubed 65 G 14mm TX with Aliaz.
Aliaz are really lacking in tactility, though. Like an old-style Gateron Brown.
*So what I’m typing on right now are OUTEMU Silent Sky stems. They are in MX Clear housings, 60 G TX 14mm spring, 3204 on stem and upper-housing. The Silent Sky / Silent Forest was the OUTEMU custom silent line before U4 Boba. They are explicitly meant to be silent Ergo Clears. So if you can just about tolerate a Cerulean, these are similar. Except you can run them at lower weights with lube, making them lighter. Mine are like a Silent Brown, kind of, or a silent CAP Brown.
The original Silent Sky / Forest housings were flawed, but you can just buy the stems from Gazzew and put them in something better. Cherry / TTC for lower tactility, or Huano Banana / AKKO CS Sponge for more. Boba housing for max. You can even make a light and poppy version in the Aliaz housing, 52 G OUTEMU springs, lubing only the stem + spring.
Silent Sky is a versatile stem that can be dialed up or down. And you have those other options. Kailh recently came out with so-called “Midnight” silent tactiles, which are affordable medium-tactiles. Beware, they may break ABS keycaps. And then there’s Silent Lemon, of course, which I receive in June.
So if Silent Grey doesn’t work out for you, it’s not a big deal. You have options now. I talked about Silent Sky because it is of a tactile intensity that might work for you.
