Choice Band or Expert Belt

Leech Life
Aqua Jet
Filler/Coverage

Choice if you are nasty, Expert Belt if you want to hit for coverage. The item really depends on when and where you want to use him.
Choice if you want to lead or mid-game to take out speedy things that don't like Water or Bug Priority. Expert Belt for mid to late-game sweep to clean up.
Go real late-game sweep with him as an ANCHOR so you don't have to worry about his ability cutting his life in half. If you can have the rest of your team clean up any potential counters, he's pretty dangerous.
