As to your question of who to see, spend a load of time on here reading the NE reviews, then make your choice. Right at the moment your going to struggle to find a good WG available the same day, there have been a lot of retirements of some of the best girls in the region recently, so it's more difficult. A week or two ahead and you should be OK as long as you don;t want to see Brooke Knights.
