I think getting a good cover scent is really important, if you get a good cover scent then...
The scented one will make people inhale deeper, so the scented version always work better than the unscented,
There is a lot of comment said the unscented one is not as effective, which is mainly because we do not always "smell" other person when we first met, we mostly look and speak with this person to judge, except if there are a very nice scent, which encourage people to smell, as the more they smell, the better the pheromone effectiveness, so the cover scent is very important.
But I don't like AV scented, because it is too much for me, while using it, people will call you "Cologne guy", and they will try their best not to smell you after they get fed up on your scent.
Scent of ero, which is not a popular product, has the best scent, make me feel very comfortable, L2K leather and steel coming up closely second, Wolf is the third.
Only the Brave cover scent is highly overrated, it may smell good at first, but then it get offensive over time, since it is "only the brave".
Just my 2 scents,
