Screw listview, use the website version. Much quicker, and no worries about wasting buffs you might have.
But, as posted before, your weapon is pretty damn good for your level. Maybe a malignant war mace(sk only 1hb, like 500 to 1kpp tops, I think) to replace it, assuming your 1hb is maxxed.
Your job is tanking though, so ac is far more important. Upgrade your armor to deepmetal (or better, if available, affordable), aug all that new armor with ac augs, finish the MQ aug, get a charm with ac (guardian a good choice), finish newport 4 ring, and upgrade other ring/earrings for items with ac on them. Also, consider trying to start work on your diety augment, and do more work on your blackscale augment.
Doing those things will serve you far better than a simple weapon upgrade.
