I use nearly all fingers, but where i really suffer is that i find key-combinations, notably alt+ to be really awkward because my hands are at a steep angle relative to the straight keyboard.
I live in Kakoune (vim-like) so "touch typing" is my bread and butter, but home-row just feels so bad to me.
I keep meaning to try a split keyboard with home-row. I suspect that's the root of my issue, and that my odd typing pattern is a result of trying to manually replicate a split keyboard. /shrug
