Lass, you have my undying respect and admiration but I see it a little differently, and please forgive my cynicism in advance.
re #1: concur, but my best guess is that the average LV local who does post here is generally substantially more affluent than the average poster nationwide. P4P is generally limited to escorts, as there is no FS MP action that I know of here, and being a tourist driven market, you're going to pay more than in other locales. Average escort services, at least from quality providers such as yourself, run at least $100 more on average than LA, with, in my experience, less quantum of service.
re #2: also concur, but who here would not know better? I'm guessing most who can find TER or TBD would know better than to look in the Yellow Pages for action.
re #3: Vegas is totally about getting paid. I'm not here for the culture, the desert sunsets, the mild winters. I assume you're not here for any of that, either. As for your "largest % of reputable ladies" theory, where would your starting point be?
My experiences, maybe I was unlucky, but many ladies wouldn't see me once I told them I was a local, then I started meeting others through business and others. So I decided to give up trying to play here. LA and elsewhere, particularly Europe and Thailand are different.
I'm sure you agree, but put yourself in my shoes. You meet a porn star at a party, with her husband, and they're asking you if you know anyone looking for privates for her. Or you are intro'd to an escort where you get your hair cut-AND her 8yo son-and you're supposed to play stupid even though everyone in the salon knows you play.
With professional girls, I think it is best to be on one side of the fence, either see them professionally or be their friend. With the former, a friendship may well develop, but with the latter, it's awkward to want to make a date. Perhaps you see my problem here. Of these people I've discussed there is a Wyatt Earp mentality (family is family, all else are strangers) about the LV escort scene. I don't see myself complimenting the porn star's oral technique to her husband, and the fantasy which escort services are supposed to provide is marred by me playing with the kid I'm supposed to pretend does not exist. So, I'd rather observe, particularly when, again in my experience, it's staggering to discover how many of the ladies who work in Vegas are married. It's just not part of a lifestyle I want any part of.
To be fair, there are many quality ladies in LV, certainly many more than when I first showed up 5 years ago (to wit, Logan, Jade and Kit and their fellow Desert Delights, whose names escape me at this moment), but it doesn't change how the game in general is usually played.
