Can't be that hard to change back the tour if your conversions took that much of a dump. I don't know why you just didn't add this one as a second tour to begin with, but 20/20 hindsight would be awesome for me too.
I've used AVS sites quite well in the past (haven't touched them in years, but still gets some checks here and there), but I used them to drive the traffic to my paysites, not in place of them. I need to get back into that.
She's a hot girl, if you've got a ton of content of her I wouldn't go completely AVS with her at all. If you've got some fetish type content of her, or can still shoot her you can make some serious bank selling clips on clips4sale.com but gotta do a fetish angle for that to work.
Good luck.
