Even when you take into consideration the fact that everyone has their own definition of what makes a tickle session memorable and worthwhile, I have no qualms whatsoever in recommending Faith as one of the top choices to spend some quality tickle time with. I should also point out that she is very good at working free from her restraints - or at least getting some wiggle room - and tickling back, as shown in the photo set, page two.
I have never met Sydney, so I can't say anything based on my own first hand experience, but I seem to recall that Faith posted about a double she did with her awhile back and vouched for her ticklishness. I'm sure Faith will be along in her own good time to comment. Also, if you have not done so recently, check out her profile page, about half way down (hope the link works):

Get an e-mail off, and voice your appreciation. Along the way, mention some ideas, and drop some hints. After all, if you don't ask, you don't get...

Couldn't agree with you more. Mya gets tickled a lot, so I have no doubt she would jump at the chance to get on the other end of the feather, so to speak. As I mentioned to dtrell above, Faith will tickle back when or if she can work an arm free. Guaranteed.
And, like everyone else, I would have given my eye teeth to have been there, even if only as just the non-participating photographer...
