I've also not read all the pages, but have looked on p1, a thought here is that the categories suggested by OP are a mix between physical characteristics of the wg and her enjoys/ services. Sometimes a girl might provide one punter with different services to another (especially certain EE's!) In terms of services, these might already be available to search upon - via AW today, by selecting girls based upon their enjoys list. Their physical attributes might not be so easily searchable on AW though.
I can see problems with punther's idea, as Dani initially pointed out, but dont mind completing such a step, in writing a review, if Admin decided to go with it.
I do see some issues with how girls might be categorised, by different people, especially if they are borderline, eg big tits etc. Some might prefer natural to enhanced, should that be a category?, what about if people are not sure of correct category?..... etc etc
I would try to ensure making the process of completing a review on here, as straightforward as possible, to ensure people felt confident about completing a review in the first place, with minimal difficulty. It might be best to limit the drop down lists, to just a few, (at leas6t to begin with) - even if that's not giving all the information we might seek in all cases!
