Been like this for a while in Hatfield now.
My impression of this lot is that there's 3 or 4 SPs in the flat at any one time, though more show as available on AW. The one you want may, or may not be there, so you get whoever is available.
Too many mediocre experiences with this lot, so being largely restricted to Hatfield for my exploits I tend to just go for a 15 min 'quickie' with them (I've reviewed a number of them now).
