While typing 'descent' today, I noticed that I was struggling with the SC same-finger bigram. No wonder, it's quite common and not easy out of the box. So I thought we could debate which bi-/trigrams we find awkward on Colemak(-CAW) and whether we have good ideas to handle them more easily.
C has a somewhat challenging placement in Colemak. On a normally row-staggered keyboard the Angle mod makes it easier to hit, but it's still lower row and might've been elsewhere if not for the convenience of keeping ZXC(V) together?
I think I'm better off typing SC by sliding in the ring finger for C. I've tried it a bit and it seems much nicer. I'll consider whether it's worth training into muscle memory.
