Turns out they did another run and I picked some up! And... they're a mixed bag IMO.
Straight out of the bag, they're very loose, rattley, scratchy, and inconsistent. There were 2 out of my bag of 20 that felt tight enough to not rattle, and actually those felt pretty good. I stuck them onto my tester next to some YOK pandas as a comparison, and I have to say, it's very similar. The weighting is of course heavier on the Tacits; and it feels like there is more resistance on the upstroke vs the HP. It's like on the Tacit that the down-stroke force to clear the tactile bump is the same as the up-stroke force, whereas the HP goes a little more linear on the way up.
However, I knew going in that 67g is a bit too heavy for me, so I'd want to spring swap, so I decided to play around a bit to see if I could get them some of them into a better state. This is where things really started to get interesting.
I popped a couple others open and swapped in some 60g springs from some donor Cherry blues. I found that while the weighting was better for me on these, the tactile bump become too big. It feels like it was tuned for the 67g spring, so with a weaker spring that increased tactility on the up-stroke felt almost like the switch kept sticking. So overall, not bad but not great either. I also tried applying some Krytox 103. This definitely improved the feel, but on some the scratchiness was so bad that lube didn't really help.
I knew that I was going to need switch films to help these, which I don't have--so I'll have to order some. Then on a whim I decided to try putting a Tacit stem into an Aliaz 60g housing. HOLY ****! I haven't even lubed these yet because I was too excited to go write up this discovery. Immediate MASSIVE improvement! The first thing I noticed about resulting switches--Taliaz? Alicit?--is that they felt buttery smooth. And the BUMP! It's definitely toned down compared to the stock Tacit--a little less forceful, more rounded and less crisp. It also feels a bit rounder than the HP. It has more of a big bubbly "pop" feeling. IMHO it's the most Topre-like I have experienced yet on a mechanical switch. And the return force feels very smooth too--even more linear-like on the way up than the HP, but still enough to feel it. It makes for a sensation that is very lively--not slow or sticky at all. It's FUN to press on it! Just to make sure I wasn't going crazy, I put it next to a Zeal v1 (I don't own v2s) to compare. The tactility is still there--the Zeal feels almost linear in comparison.
I don't think this frankenswitch will totally replace the HP for me--I like them both for different reasons. For silenced builds though, yep, this one is endgame!
