If your intent is to be fully mastered, i'd be switching to Grenades and focusing on them at this point. Seems the most effect place to do this at your level is Tormenta Cave.
Edit: What Savvy said
the smoke bombs/firebombs grant you the most rep per attack. Stink pots tend to do less damage and may provide MORE attacks and thusly more rep.
Otherwise sailing/cannons on big ships
