I use 25g light blue, which I think is perfect. If you're experimenting, the heaviest I'd try is 35g pro red.

It's an interesting challenge, I've only been learning a few weeks after work and my record on monkey type is 35wpm. The hand swapping skill is something thats unique to the layout but I'm starting to get the hang of it now. With light switches, and some practice it's starting to feel like the alphas and special characters are instantly accessible since its only combos and no layers. As a programmer that's going to be really useful. Here's a YouTube video of the creator typing random ASCII at 53 wpm! https://youtu.be/A_NVzUSEAxM
I think it's a good idea, I added chords to my keyboard with zmk and I found it more comfortable and accurate than the CC with its multi direction contortions.
Yes, I stopped using it and went back to normal keys.
Probably a fight pad for street fighter etc.
With the 25g I can only rest about half the weight of my fingers on the keys without triggering something, but with the 35g I can rest the full weight comfortably. If I'm practicing a lot then I do notice my fingers get sore after a couple of hours on the 35g, but for normal use it's probably fine.
