Questions regarding builds

[Premezilla]

I'm looking for a build that will be fun to play as, and that will use items that can be easily found throughout the course of a game. After discussing it, I've come down to some possibilities:

A combination of a Rogue Reject that uses poison (Uses sword/bow combination, both socketed with either emeralds or the runeword "venom")

A Zookeeper Tank (Druid who is beefy enough in that he doesn't need to transform, who uses lots-o-summons and dabbles a little in elementals)

A Double-bladed barb (A barb who uses WW and Beserk)

I have already tried using the Barb idea, but have messed it up many times (Too low attack rating, too low vitality, etc.) so that's kind of out, but the other two seem fun. If anyone has any ideas, please leave feedback, such as new ideas, refinment on mine, etc. Also, please keep in mind I probably won't have access to unique items, only what would normally drop in the game.
Also, as far as mercenaries go, I was thinking of the tried-and-true holy freeze merc from act two....but ideas are appreciated.

Thanks much!

*EDIT

Thanks much for the feedback about mercs...

I was thinking of a way to somehow tie all of the different ideas into one, and bingo! I got it! Here we go....

Being the Daughter of a Navy Barbarian and Amazon couple, Randiela (couldn't think of anything else, so I just used everyone's favorite poison-spewing baddy, Andariel) experienced the harshness of the battlefield at an early age. Brought up to use both dual weapons and ranged attacks effectively, she soon grew well-recognized among the ranks of the Westmarch Navy. She soon outranked her parents, which caused a bitter feud among them. Cast out into the world, she wandered aimlessly from one platoon to the next, until the fateful day The Wanderer struck down Diablo. The very night Diablo had been vanquished, she was overcome with madness, and sent to the damp catacombs of the Rogue Encampment in Ensteig, in hope that she would someday return to her former glory. That was not to be, for over time, she developed an affinity for the damp, mold-like cells of the catacombs, and soon took the name Venom as her own.

However, all was not well. Diablo, believed to have been cut down by The Wanderer, was rumored to walk among the living once more.

Yada yada yada, you guys get the picture. However, I couldn't think of a way to tie in the rogue idea with the story, so I'm guessing she developed two personalities and the second manifested itself in a bow or something. (The act 1 merc). So what do you guys think? I know it's not as good as Occhi's story *nods head* but it seems sufficent. Opinions?

p.s. is this in the wrong place?
