I regularly attend these parties when they're on the West Coast(mainly the Vegas parties,but will attend the L.A. parties soon),and am always delighted at how each one gets better by every new party that comes along,and its ever-growing guests list of celebrities(of both the adult film world,and the fetish internet)that attend these shows.
Out of all the ladies I've done sessions with,I would recommend AlexisOnFire(who's both a great ticklee,and a really mean tickler),Rubee Tuesday(who's the same as both ticklee and tickler),and Danika(Imago Studio's Molly Bronte),an all-too-gorgeous LissaFeet model who's extremely ticklish. I never tickled Jacklyn Lick,but highly recommend a session a her,as well(since she's one of the more popular girls at the FWP parties).
Otherwise,attend these parties when they are in town,for both these parties' organizers Steve Savage and Jason Khan(who are both really hella nice fellows)really work themselves hard in making sure that these parties deliver,and heartily care about the fellow foot fans out there.
