Some pagelong computer program I wrote says that these are the dominant strategies:

(sword damage, sword speed) (armor damage, armor dodge)
(100, 80) (-12, 10)
(100, 80) (-20, 0)
(100, 80) ( 0, 24)
( 80, 100) ( 0, 24)
(150, 50) (-20, 0)
( 50, 180) (-20, 0)
( 50, 180) ( 0, 24)

I suppose I'd pick one at random because I'm too lazy to figure out what the right mixed equilibrium is.
