I'm trying to make my level 70 Warlock bank-toon look snazzy, and I've got the Soul Harvester (http://www.wowhead.com/item=20536) and want to see what some enchants look cool on it. I'm thinking maybe Executioner or Mongoose? But I'd rather not just throw away 400g for them if I don't like them, so is there a way to preview what an enchant looks like on a weapon?
