Non-sword 2-handers are typically the axe variety - you don't need to mod the unit file to fix them. See here: http://www.twcenter.net/forums/showthread.php?t=74094

The first post points you at zxiang1983's 2h fix, widely regarded as the best. Instead of messing with the unit file, it's just a repacked animation pack, containing working animations for the units. Happy playing.
