I looked up Gazzew yesterday and he seems to have exploded out his options, and moved from an enthusiast to an actual business. I'd noticed that he has 'P' and 'D' type stems, figure I'll just get a mix of parts to try out to see if anything appeals to me.
What's the difference between the slot and no slot housing- is it a matter of wobble or is it something else, and what's the 'slot' anyway?
The timing might be good for this, I am halfway through printing a Dactyl Manuform case to test fit, and was thinking that I'd need a bunch of switches to properly test it out.
Yeah, Gazzew has been working hard with OUTEMU from what I hear, really going through the design and testing of all sorts of new stems.
The so-called 'P' stems are the "Silent Sky / Silent Forest" or "Silent Tactile." They're called 'P' because the bump is near the top, and limited. [Kind of like Kailh Pro Purple]. It's more about there being a limited, discrete tactile event, followed by a linear keypress. The bump is actually fairly centre-mounted, almost like regular Cherry.
The 'D' stems are called that because the bump is not limited like the 'P' but present through most of the keystroke.
The slot issue is very important. I think the 'slot' refers to clearance for RGB / LED. For serious typing, this is not a consideration, and so you can get a much tighter top with no clearance for lighting - these are the 'tight-tops.' You definitely want the tight-tops. My U4 Bobas were ordered with tight, no-slot tops. And you definitely get very little wobble compared to earlier designs. It's absolutely essential to get some kind of tight no-slot top setup. That's why it's helpful to communicate with Gazzew, and he will ask what you need to do and advise you further.

Also, with regard to the Topre discussion, I can confirm that Realforce 55g sounds awesome, no need to mute that. You buy it for the thock.
[In fact, put it in a thockier case, if you can!] And get MX sliders and put PBT MT3 on it, while you're at it.
But yeah, 55 G Topre is heavy and you'll notice it if you're coming from MX Brown. I think that 55 G Topre is one of those switches that feels awesome at meetups, because it is, but it's for someone with a heavier switch preference [maybe they were using heavy rubber-domes before].
45 G silenced is much more sustainable if you're used to MX tactiles. And the BKE Ultra Lights are a serious consideration.
