Seriously, dude? Does it REALLY matter which hand the bow is in?
C'mon, we're just asking for ridiculous stuff now.
For some, yes, it does. I couldn't stand playing Unreal Tournament 2004 with my weapons in my left hand. It drove me up the wall, until I finally found the option to change it.
Besides, we already know that, for one handed items, we get to chose which hand they go in. I don't see how it should be any different with bows or two handed weapons.
