Neither. Someone with 50 50 50 50 for att, str def, and range would kick the shit out of any pure. I'd suggest getting some decent levels and if you insist on being a pure be a barrows pure (90-99 str, 80-85 att, 70 def). Or if your ranging wear void and use a darnk bow for specials and a r'cbow with onyx(e) or dragon(e) bolts.
