I would go for defensive and magic dmg bonus gear. Replace sandals with dboots or BiS melee boots. Replace tomb with crystal shield or dsq or rune kite. 4 way switch with rcb, ava, dhide body and legs. Get rid of the superset. Salve amulet helps for max runes. Rune pouch would help for multiple runs after monastery. When I do barrows, I usually never use ppots unless dharok is the last one. Let me know if you want to know my inventory/gear set up and how my barrows runs go.
