After being less than satisfied with Dvorak, I meticulously designed a layout for my personal use an year ago. I have been quite happy using it, and it is quite similar to colemak ( there is only one scientific way of placement in many cases ). Just think I would share it:
12345 67890 []
QGRPW VLUY- /=
ATSDC HNEIO '
ZKXFB JM,.;
Unlike colemak it makes no compromise to qwerty, though most characters remain on the same hand and I found it fairly easy to adapt. There are very few same finger consecutive typing, except --nl-- ( only ) , --rs-- ( verse ), --lm-- ( almost ), --nm-- ( government ), --eu--. It has comfortable hand alternation and finger rolls. "v" and "j" are better switched on a standard keyboard, but I use an ergonomic keyboard which serves better this way.
