...for those of us who touch type the "correct" way and use the side of our thumb to hit it.
That's not the correct way though - when you have your wrists in correct position, your thumb will be flat, not sloping down ;-)
I'm just joking, I hate these "you're doing it wrong" posts. I don't have any problem with convex Cherry profile spacebars, but concave SA/MT3 is a pain, the edge is quite uncomfortable. No use flipping those buggers though.
Also, great work with the wooden case!
