Bandos is overcrowded and cheap drops, but if you insist, ide get 85 attack first. Most teams require a gs and you can't even wield one..
Zamorak is a harder bandos but it's too hard to find a team and the boss hits too hard, and only 2 good drops.
Armadyl should work perfectly for you and you make a lot of money off it, plus you don't need a tank. ide just get your range to 90 though.
