1.  "Barbie" (TINY WAIST, HOURGLASS FIGURE, huge boobs, tight ass BUT A TOUCH ROUNDER THAN THE TRADITIONAL BARBIE-- my current #1 SB has it but i could only describe it better with her photo, FLAT BELLY -- the cradle where the little bones on the hips stand out, PERFECT PUSSY - a whole other discussion but to start, i prefer mine shaved)
2.  the "VOICE" (for me, both have been smokers, again hard to describe... sounds great in bed, doesn't say anything inherently annoying...again my #1 SB has it, but so does my wife)
3.  STYLE (I actually don't care if the woman is exotic or from another country as long as she knows how to adorn her body-- my #1 is and my wife was a fashion model)
4.  Educated WITH A SENSE OF HUMOR (not knowing something is funny is a giant fail)
5.  Adventurous BCD (pretty much what you said, she enjoys herself and takes risks)
6.  GFE OUTSIDE THE BEDROOM (i'm a cheeseball and like the handholding, PDA, knowing about her other life)
7. A FOODIE AND GOOD TRAVELER

We each have our own list... many overlap.  

Search the forum for "unicorn" and you will see several dozen threads.  

Not detracting from your current status.... I'm always happy when the limits on my rotation are influenced more by time and libido than by budget.  Grats!  

 
Life is good

1. Barbies are nice, but I would trade a tiny waist for slightly smaller boobs. On the other hand, my "type" is slender East Asian women who tend to be the small chested and slender ass kind of gals.
2/3 World traveler is a huge plus, especially if she was born abroad. It doesn't matter where, it just makes for better pillow talk.
4. Educated, of course.  
5. A couple of real orgasms are nice; I don't want her to fake it. If she has more, that is a nice treat and probably only happens when I am giving her oral.
6. I want to wake up next to her.
7. A lovely dinner companion who appreciates great food is more important than a great cook.

I am curious as to gals views of optimal SDs.
