I must admit I haven't been hobbying much as of lately, but over the 10 years since I started, mileage was definitely a ymmv. The way I always looked at it, the better looking,hotter (body, face, etc) MPA usually wouldn't give it up easy because they have more going for them. The, lets say, more average type MPA usually would give it up pretty much right away. That has been my experience.
To be honest, I am more or less am a true MPA guy. I like the build up, the tease, the subtleties of a real good session. If I was really gung-ho about doing Daty, DFK, Digits etc, I would just go to a SP.
I think the real "stars" of this business, personally, are the ones that use creativity, special manoeuvres, work the room, incorporate some individuality into their sessions. I wouldn't necessarily judge a good session on whether the MPA lets me do whatever I want to them. I have left some of the most intense, best sessions I have ever had and everything that went on was very much on the level.
I have been a repeat client of a few legendary MPA's and I would say that, even with the, I need not venture into these so-called new expectations because they are that good at their jobs. Obviously this is a very personal opinion and it seems on this board that there are clients from each end of the spectrum. I pretty much stick to the "elite" spas and I am very happy with what I get. And if it means anything, I am always respectful, clean and nice.
Just my 2 cents.
