why do u need a battery grip?

i mount an 80-200 with a sb600 and still somewhat okay. needa rest d next day though.

i think you should really ask yourself whether u need a bg. changing systems just for a bg is pretty fickle. your current gear ain`t that heavy either. have you tried different handheld positions? tripod,monopod maybe? just think wisely

have u considered about the extra weight of a d80+bg or 350d+bg ? it might be more painful as well.
