As I'm sure you already have Dragon Legs and you're aiming to build a fighter's torso, so what I'd suggest the player is to keep those as your main armor, but bring a Guthan's set with you to make use of its special attack as a healing mechanism.
In this way, your main armour set will not be degradable as well as offensively friendly (torso gives strength bonuses, unlike barrows). Keep in mind that in addition to Dharok's and Verac's in certain instances however, all other Barrows sets (including those with weapons) can be used in a non-useful manner.
So the top 3 options for you in my opinion The Ariel's skirt or Legs together with Fighter torso. Abyssal Dragon Whip Defender (you can also use a Guthan's set to heal you as well). Torag's Legs, Plate and Plate and Whip and Defender. This will provide a lot of defense, but in most cases it's almost redundant since you don't have to be hit as often. Averac's Brassard and Skirt along with whip. The full set can be used for certain types of activities such as Kalphite Queen and Barrows as well as PvP.
