While I empathize with those that have had to deal with false advertising, I still think perb is your best friend. If you can't find a review, and are willing to TOFTT, then so be it. Just report back, if the advertised weight was just too far off for the imagination.
Failing that, just don't go see anyone that hasn't been reviewed, at least somewhere in the archives! You absolutely deserve to have a happy experience but, just as in real life, there are no absolutes here in playland! And weight is only one aspect of the experience.
Don't worry, eventually, you'll have your very own personal list of favourites, and they'll be on your list because of your valiant efforts at sorting the good from the bad, based on what makes you happy...
