Downwards I think, though I've never really thought about them like that! I think on row stagger there are also ones I like more than others, right hand sfbs especially when you slide them on a low profile (laptop) keyboard feel a bit more natural than left handed sfbs in that sense

Good question.

In my case downward ones are more comfortable.

Also [carpalx](http://mkweb.bcgsc.ca/carpalx/?typing_effort#typing_stroke_path) rates downward progression as more comfortable.

I can definetly type upwards faster so I would choose upwards.

Do you prefer having same-finger bigrams go upwards on the keyboard (like LO in the word "low") or downwards (like ED in the word "ted")?

I personally prefer downwards by far, but I wanted to hear y'all's opinion on this

Do you prefer upwards or downwards same-finger bigrams?
