Did you ever try Colemak? I've been Colemak for probably 5 years now, I can't speak to pinkie specific pain but I get much less tired on long typing sessions. It's interesting to me how everyone seems to know of Dvorak over Colemak. But I never heard of BEAKL, thanks. For me the issue with Dvorak was that I wasn't ready to give up my function keys (control x, c).
