Protection aoe grinding tips

Since hitting level 41 I've switched from 11/0/21 to 11/21/0. Using a mithril shield spike, ret aura, consecration, and blessing of sanctuary I can aoe 8-10 mobs with ease without needing cool downs. Each pull I get about a 1/4 to 1/2 bar of experience depending on level of mobs.
Does anyone have any tips for this method of leveling? Any gear or items to look for? Talents? Locations? At my current level it's difficult to find a location with good mob density that isn't too low or too high of a level. I know once I hit EPL and WPL this will go quicker with holy shield at 51.
