The thinner red ones will be fine.  The blue/black ones I think reduce the travel too much..but some people may like it like that...

From the WASD website, it says that red O-rings are .2mm and blue/black are .4mm. I have a sampler kit and I prefer the reds the best.

Either one is fine. When I put 2, even thinner than WASD, keycap pops up when I spam too hard  :p

I have some WASD o-rings and calipers. 1.4mm for red, and 1.8mm for blue and black.
Keep in mind that's thickness. Travel reduction is less than that because the o-rings are round and the keys don't land perfectly on the vertical diameter.

Here's what I had in the past. The WASD thicker ones are the "A" size, the thinner ones are "H". The ones you'd want for imsto's thick PBT caps is the "D" size. I found these are the thinnest you can have them while still being effective as O-rings. If you put these on normal stock caps, then do nothing because they're too thin to even hit the bottom. On the imsto caps, if you use any size other than "D", you get a significant reduction in travel distance.

The "D" size is 1mm thick.

Which of these are IMSTO's silicone o-rings?  I'm guessing the thickest red and the second thickest?  Not sure where to find D. (Will look for your original post).

Unfortunately, almost all non-keyboard O-rings are for industrial purposes and are much harder than what we want.

"Starting in 2011, the deficits again started to shrink. During Obama’s term  the deficit was reduced by $900 Billion  before finally in 2015 the GOP managed to wrangle a “reconciliation” bill out of Obama where he again cut corporate taxes, as well as made permanent some of George W. Bush’s original tax cuts. This is the year everything reversed. Before this, under Clinton, Bush and Obama the deficit in almost every year was gradually decreasing. The balance we had of taxes and the economy was bringing the deficit down, the money coming in was slowly catching up with the money going out until 2015. Trump’s subsequent tax cut has continued the new trend even after the rest of Bush’s cuts have since expired. Obama had an average GDP of 2.3%, with 11.6 million jobs created and unemployment peaking at 10% in 2009, then falling to 4.3% in 2016. If we had continued on that downward deficit track, we would have again reached balance and another surplus in 2017-2018.

Actually, it depends. I don't like them (linear Cherry MX + Cherry DS). Technically, it would be possible to use even the black o-rings, though.

70A o-rings exist, but they're usually either too big, or too small. I wouldn't mind very thin, this hard ones only to slightly dampen the sound. I don't want reduced key travel.

Oh.. yea, of it's possible..

On my oem profile pbt, I was rocking 2mm silicone ghetto-rings, which reduced travel by 1.3mm or so. 2.7mm travel is close to the lenovo scissors

It won't be like the new Apple scissor which honestly feel like 1mm travel.

The only issue is thick pbt because it's cherry profile, so there's not a great deal of room for the orings..
