The two are pretty similar, but to me red pro is just about the point where I can hold the key without thinking about it, which is a good trait for modifier keys.
Originally I used numpad as a navigation block, but I’ve since figured out that setting right thumb row to [MO(2)←→↑↓] / [▿Home End PageUp PageDown] works well for my purposes, so now it’s just chillin’.
Assembled (complete with the pleasantly smooth photopolymer SLA case) by a local company (splitted_space on Telegram), originally with brown switches.
I’ve seen that there was a tiny trackball mod for Sofle, but cannot easily tell if any changes are necessary to get this working with Choc.
Myself I’d probably want a bigger trackball like fingerpunch’s Faux Fox / Rock On builds have it.
