Finally. My love of the sweep has proven to be correct, two thumb keys is the way. I am using a ZMK powered Urchin, a sweep variant, as my only daily use keyboard, 34 keys of love.
I think retaining the number row and the outer pinky column makes it more accessible; but I find it odd the design then also removes the lower row of modifier keys, and only gives two thumb keys each.
It's good to use the thumbs more than the pinky fingers. -- But, I'd think an introductory keyboard would retain modifier keys for the pinky fingers to use.
