If you are talking about PVP, the successful melee stam NB's I've seen tend to either use heavy armor or roll dodge constantly (which is a bit more challenging play style).
I take it you are looking to manage longer sustained melee fights rather than ganking? Haven't tried that playstyle yet on my NB but I know a lot are still using heavy armor.
