So mine just arrived - here are my thoughts:
First impressions
62 G
Still has a lot of that insectile sound, but the new housing makes itself heard. It’s a bit deeper and flatter than recordings of the old V1, even stock. It is a high-pitched chittery sound even compared to something like Gateron CAP Milky Brown, though.
These aren’t lubed much from the factory. Clearly intended to be user-lubed. I would say that they are underlubed, if using Gateron CAP for comparison. They actually feel a bit scratchy, and you can distinctly feel the entire process of the tactile leg. You can feel it catching if operating the switch slowly, kind of like Ergo Clears that haven’t had much lube.
If coming from today’s heavy tactiles like HP and Bobas, you might mistake Zealio V1 62 G for Browns. But they are not. Stock Zealio V1 redux feels more tactile than lubed Durock Medium Tactile, such as Mode Signals. I would say that these ‘62 G’ springs are pretty light for the size of the tactile bump, kinda borderline.
It’s a small, crispy bump that isn’t as ‘rounded’ as MX Brown or CAP Brown. It’s definitely a less ‘chill’ switch than Browns are. It’s a ‘sharper Brown.’ It has a more abrupt tactility.
I would definitely want to lube these, gonna try 3204 eventually. I also wouldn’t want to run these on a metal plate. I’m testing on a Tester68 board with GMK, and it’s a bit harsh as you are likely to bottom-out. I think these would be better on an MK870 with polycarb plate, or even a plateless Cherry-style build such as NCR-80.
67 G
These are noticeably heavier than the 62 G. Not as smooth as the 67 G Zealio V1 original that I remember from meetups. But those were carefully hand-lubed.
The 67 G feel much more directly-comparable to Durock Medium Tactile. 62 G Zealio V1 redux feels lighter, in terms of spring-weight, than 63.5 G DMT. The 67 G Zealio V1R feels maybe a bit heavier than DMT in terms of spring. Tactile bump intensity of 67 G Zealio V1R is comparable to DMT, but you would have to closely line up a bunch of switches and carefully test them to suss out the differences.
Conclusion
The bump is comparable to Durock Medium Tactile, but spring weight is a little different. Factory lube is very light, given the size of the tactile bump, which is larger than Brown. Probably a little more intense than Gateron CAP Brown, and definitely less-rounded.
You might call this a “light-medium” tactile, and one that should be lubed. Definitely more intense than Brown-style switches, it is a kind of light Ergo Clear. I remember building some Gateron Orange stems inside Boba housings with 60 G L TX springs that kinda remind me of these. I actually think 16mm springs might be beneficial for function with these, since the lighter springs need more weight at the top. I have yet to try that.
There’s some crunch-noise or plunger-noise from the springs and/or central housings in operation, it seems, at least unlubed.
