I use purpz on pinkies and thumbs, then silvers everywhere else. I can see how the 10gf differences between Reds and Silvers might not seem like a lot, but it was noticeable for me. There's also the Pro Reds which are slightly lighter at 35gf. After that you're into pink/purpz range which might be too light.
I don't know the optical ones but maybe this helps:
Kailh Choc
Red Pro: linear, 35gf
Purpz: linear, 25gf
Light Blue/Pink/gChoc: linear, 20gf
All have 3 mm travel and trigger at 1,5 mm
Eh, kinda. The optical reds are apparently rated for 45g, as are my gateron reds on my Q1. I just remember the switches on the huntsman feeling super smooth. The silvers in my tester kit are pretty dang smooth with just a bit of resistance. Might go for some of those since the pinks feel just a bit too touchy and the crystal reds / choc pro reds feel pretty similar to the silvers.
Ergonomic, split and other weird keyboards
Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)
i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²
¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid
