Calii... you know that may be an idea.
WnG, I remember Mara saying in response to a post I made a while back that mones have memory. So what you could do is wear the mone that you have decided on around your target and then leave something behind that has the phero free scent on it. That could possibly trigger memories.
For example if you had LFN in Nola. Wear that phero blend around the target and then leave something behind a scarf, something that is scented with plain Nola on it.
