due to my situation my priorities go like this. Those that I want to see again, and mixed in by availability and funds ones where reviews, board persona and looks (petite, dark hair and feisty) determine the order of my longing.
Nothing a ton of hundred dollar bills wont solve.
My favorites list is now 7 pages long! lol! I would truly love to meet them all, but I know that's not realistically possible.
Here is one thing that helps me choose a provider. Like you, chemistry is king for me, so I love it when a lady has a blog on her website. It gives me some insight into her personality and helps me determine if we would be compatible. That's what sold me on my regular provider. She was the first provider I saw when I entered into the hobby, and I could not have made a better choice. We've been seeing each other for almost a year now, and it's been completely lovely.
I have branched out a little here lately and seen a couple other providers. The problem I'm running into now is that I adore all these ladies and want to continue seeing ALL of them on a regular basis. I only wish I could, but unfortunately my budget won't allow it.
I also go off of the ladies reviews. If most of her reviewers only talk of the act itself and little of her personality, I would probably pass. If however, a lot of her reviewers talk about her charm, wit, intelligence, grace, sense of humor, etc. , that will definitely get my attention. Again, the chemistry thing.
The only suggestion I can offer is to enjoy the ride. After all, wanting to meet and spend time with a LOT of lovely ladies is a pretty damn good problem to have, isn't it? ------ Rober
Well, you could have whittled your list down a fair amount this week in Raleigh given that there were five porn stars here for a few days last week: Aubrey Addams (petite and busty), Amber Rayne (medium-height and thin), Faith Leon (tall and a cover girl model), Lexi Love (petite and blonde), and Tessa Lane (tall and curvy). Save up your money and, just like the planets aligning ever so often, good things eventually happen. 
There's nothing like spending a lot of time in southeastern NC to keep a wish list nice and narrow. Yes, there are some fine ladies here, but it can be pretty tough to arrange a visit without lots of advance planning and driving. Having spent some time in DC myself, my advice to you would be that you not try to be like a kid in a candy store thinking you have to sample every flavor they have there when you know you really like chocolate truffles the best.
