I'm going to give this the benefit of the doubt and assume you're not trolling. First off, the ladies are generally referred to (at least here) as SPs (service providers) and not SBs. Secondly, since what makes someone good is very subjective you'd need to be a lot more specific about what someone who i "good" means to you (looks, age, race, language, services offered etc). Latsly, when you have that idea in mind you should describe what you want in the Escort 411 section and you're sure to get some recommendations, rather than asking in the lounge. You can also consult the advertisement threads to see ladies from here, what they look like and what they offer, as well as agencies that advertise on the board.
