Assuming a standard QWERTY layout, shouldn't you be using the left shift when typing < or >? It'll significantly reduce the contortion effort in your right hand. Same goes for most chords- use opposing hands for the modifier and symbol keys.

(Oddly enough, I don't bother doing this with ctrl/cmd + a/s/f/z/x/c/v, but I think that is mostly because keys to the right of the space bar vary so much between laptops and keyboards that I never bothered trying to stick with it).
