I'll be taking a Freestyle class at 7pm at PolelaTeaz, but you'll have a blast in Jiggle It – Dorothy is a hoot! Maybe I'll see you in the studio though!
I've only taken an intro class at S Factor, but didn't stay there – they have a whole Zen/no mirrors/spiritual thing going on over there that I found to be a little disconcerting when applied to poling.
Ego Fitness I can recommend, try a class with Crystal Belcher aka "Little Crystal", she's a firecracker and will make you work pretty hard. My favorite drop in with her is PoleworX/Sensual Stretch. You'll always need sneakers here, so don't forget to bring them, and beware Ego's very unkind florescent lighting… I always try to wear capris there, where at PoleLaTeaz I feel okay to be more daring because they dim the lights down to make it more sexy.
