just curious what type of metal do you play?metal covers such a broad area.i play mostly slayer and mettallica,but i also play testament,pantera,suicidal,and even some motley crue and ratt(very little of those)of course i write my own stuff which is about as aggresive as slayer but i don't stick to the chromatics as much.i feel like the more aggresive the better but it has to mean something it can't just be mindless bursts of speed.the point is i have tried em all as far as pickups are concerned and the type of metal you play is going to determine the best pickup choice for you.for what i play emg's are the best(81 at bridge)but for ratt or crue a duncan jb or screamin demon is pretty cool.if you don't want to go active a dimebucker is the most aggresive and articulate passiv pickup going.just make sure your bridge pickup is high enough output for the metal you play and the others can provide the versatility your looking for.
