I'm one of the few ones that will NOT buy catfights with no-nudity, despite the intensity of the fight. That is why I don't buy anything from IFW and almost anything from Socal, (and I hope will not have to include SF in this list soon!).
I think no-nude fights will not increase SF's sales, conversely, it will drive loyal customers (like me) away. I can't imagine anyone currently not buying a SF video because of the nudity, but I'm actually sure there will be at least one customer not buying any no-nude SF catfight: (me)
Anyway, I understand SF is a business, so "money talks". Let's see if sales are aligned with the poll results.
