My brother swears by Standing Estrous. At $45 a bottle, or whatever it is, I'll pass.
I've seen more activity from Special Golden Estrous than I have anything. The only other I've used is Code Blue.
I personally don't like messing with scents. Seems to be a lot of trouble for not much gain that I've seen. The easier to use and less mess is an important factor to me though. That's one reason I like the Special Golden Estrous, it has a spray bottle.
The stick (like a deodorant) VS1, looks interesting because it should be easy to use and not messy. Not sure on price, haven't heard.....just looked it up, it is $45 a stick too.
