I disagree with most of what you say: I find it lasts reasonably well (~4 hours), has a lot going on aside from leather (a fumey oil note, a soggy organic woody sawdust note, a "noisy" note, etc) and fell in love without any self-inflicted arm twisting. What I agree with, though, is that there needs to be a Dzing! EDP.
On another note (ha-ha), every now and again, I get a "diaper note" out of Dzing. Not soiled diapers, mind you, but the factory smell of diapers when you first tear open the package from the store. Guess I'm just grazy.
