with booker gray, and they were mostly negative.  He is the king of B & S.  He advertises girls he doesn't have who are working elsewhere, which means he has to still go through the real booker for the org the girl is working at, OR, he has to switch you to a girl he DOES have available himself.  Guess which one is his first choice?   The only one that went okay was a completely independent former Kgirl who was working out of her own incall and had agreements with several bookers to book for her.  These usually require a call back to confirm from the booker because the booker has to find out directly from the girl if she is available at the time you request.  

 
In all fairness, my experiences were the first few months he showed up on the LA scene.  He may have cleaned up his act, but I haven't heard any glowing reports that would make me change my mind and use him again.  Just my opinion based on my own experience.
