My honest opinion would be that you can find attractive girls in a lot of places. You'll find a mix of attractive and not-so-attractive MPA's working in most places. I could go on to name who I think the attractive ones are but that would be just an opinion. You could go look and totally disagree with me, or anyone else.
As far as the best line-up of attractive girls, in my experience and opinion, it is HFH. Having said that though, I haven't seen any of the current girls at IT and I've never been to Allure. So I can't compare. Another place, mentioned earlier in this thread, happens to employ two of my four current favourites.
