I found that if I was in a party synced to stupidly overhunt them like people tend to do in the Mire - I had naff all chance of landing a light shot on them. If I was in a party synced slightly higher (but still getting decent exp) - I could sleep them pretty reliably. It's the old IT++ mentality that plagues places like the Dunes that creeps back in for Impy levels.
