I have a Salvation. I agree with a full plate it’s similar to a Bakeneko (which I have), perhaps a little more lively. Nice feel and great sounding, especially the spacebar. You can type on it very hard and get essentially the same experience as light typing on a firmer gasket mount board, so it can be really comfy.
If you want it livelier in plated config, you can move the pads under the leaves. I still would not describe it as bouncy in that position, but it does give it more feedback than a Bakeneko. A config I liked for a while was just the spacebar-adjacent supports in the standard position and the rest in the bouncier position, preserving the punchiness and sound of the spacebar.
However, my main build is plateless with a Hiney H60, and it really does vibrate significantly without a plate. Very different experience and much more vibration than a Bakeneko. I don’t think I’ve tried a board considered bouncy with switch plate or PCB leaf springs, so it’s hard to compare. I wouldn’t descrdibe it as bounce, but it does give a lot of feedback, much more than plated.
Haven’t tried it with the flex-cut PCB. I assume it will be a fun novelty but not the way I’d normally want to type.
It’s a neat board, not world altering, but I enjoy it, and it is unique. Definitely worth the low-$200s sale price if you have a use for it. I wouldn’t be surprised if they still have some next sale.
@pixelpusher I’m unclear if you’re using both the “standard” and side screw mounts, but you only need to use the screw mounting holes at the Tab-Q and \ positions, if they are there on your PCB. The ones on the edges are only provided in case the PCB lacks those two. I think it would make it stiffer than it needs to be or noisier to use all four.
EDIT: You know, after writing this, I went to type on it, and I’m finding it vibrating less than I remembered even with no plate, more like an o-ring board. I recently switched keycaps back to NK PBT, which are beefier than the caps I’d had on recently. I think things that affect vibration transfer to your fingers make an extra difference on this board.
