Watching Kristin Cavallari straddle the back of Justin Bobby's motorcycle on tonight's Hills gave us deja vu -- and apparently, we weren't the only ones seeing double. After taking Kristin for a ride on his bike, Justin joked about refusing to retire Audrina's helmet. Fortunately for him, Kristin laughed it off -- and explained she has no prob whatsoever inheriting Audrina's hand-me-downs.Since the new and improved JB has us feeling all nostalgic about his dating life, we thought we'd cut to the chase and find out which Hills gal you think makes the better biker babe. Think Audrina still belongs on the back of Justin's Harley? Or does Kristin seem more comfortable around his stick shift? Take the poll and tell us who looks hotter in the hot seat!
