I remember the Cusano 18 maduro's being like that - but IIRC it wasn't due to dye though. Will, I think you suggested at the time that it might have been because the filler/binder was some sort of old maduro wrapper (making it the 18 year stock) and the maduro wrapper was just very oily. Since then, I've had some Camacho triple maduro's that were more oily (oilier?) than normal and I've thought that maybe it was the same reason. Love those triple maddies though - they burn bad most times but their taste makes up for it.
