I can honestly say I have only used one attractant that has worked. Golden Estrus by Wildlife Research, and then ONLY when the rut has started. Not when the bucks are making scrapes/rubs, but when they are actively chasing does.

As far as other scents/pee etc goes, I think ones best bet is to leave em at home, but that's just opinion. It also depends on hunting pressure. Relaxed deer will be more prone to come in and check out a new scent vs. those that are pursued hard. Deer pee is nothing special and I don't believe it's gonna make or break the deal.
