Washington DC
Great question!
Here are some possible recommendations for you, but they are certainly not in 'rank order!'
1. 21-year old petite Nikki of http://www.ultraGFE.com uses a smooth, south Georgia technique during DFK, and is even better if you bring her some vodka and cranberry juice to 'break the ice,' and get to know her better! 
Nikki is $$1/2, well-reviewed, and arrives in DC on 30 Nov, as I recall?
2. Petite and sweet all-natural Molly of http://www.msgoodgolly.com ! Molly is also well-reviewed, and uses a nice full-mouth technique, and again, her DFK becomes more intense and satisfying if you allow some time to get to know her better! You will be well-rewarded, as Molly has a genuinely sweet spirit!
Molly is $$$, and arrives in DC on 7 Dec, I believe?
3. Petite and cute Mandy of http://www.ultraGFE.com has a darting, swirling-tongue technique, that slowly transitions to a fine BBBJ before you know it! A fine MILF deal at $$1/2, and I think she arrives in DC on 6 Dec?
4. Luscious, well-reviewed, and big-breasted Gabriella of http://www.beauties-of-eden.com ! Gaby enjoys a bit of Bacardi 151 and coke to better relax, and her DFK technique is pure Hungarian...slow, wet, intense, and full- and deep-tongued! Gaby is $$$, and I believe she arrives in DC on 8 Dec?
5. Cute and trim blonde Ashley Taylor is also a very good DFK choice, but I do not think her website is up yet? You can read her Reviews on TER, though! The backchannel intel is that she may arrive in DC on 13 Dec, and you can e-mail her direct at [email protected] to check on her DC tour rate?
...
Good luck on your noble Quest, and Happy Thanksgiving! 
dc!
BTW! I think connoisseur originally derives from the Latin cognoscere = to come to know, and I think you may well enjoy 'coming to know' any of these lovely ladies!
