The guys I play with can do either method consistently without wiping. Swords seems a little easier because there are four in the middle covering adds rather than one or two. Plus, if you do happen to lose the aura, you're right there to pick it up again. No big deal. Do what you like. If it works for you, great. If not, do it normal. But if you are continuously wiping with either method, change the method or change the group.
