You shouldn't make a twink hunter at all.
The best is to make a PvP class, because it's twink, you equip with uber weapons (and enchants) for huge damage. I say rogue is the best, they have dual-wield so you can equip with 2 very good weapons and beat the crap out of everyone. For talents on a rogue (lvl 19) go:
Malice: 5/5
Improved Sinister Strike: 2/2
Improved Gouge: 3/3
I pwn everything like that
