I'm very happy with the matias ergopro and am finishing up a design for a slightly larger than full size split keyboard using matias (alps style) switches. I'm adding an extra inner column on the left and right sides with duplicated keys from the other side. I got used to using either hand for those central keys on a normal keyboard so being able to use them that way on a split seems like a good thing to me. Since it's bigger, it'll be a bit pricey to build so I'm tempted to throw together one of those tiny keyboards with the reversible PCBs just for fun.
