Exellent guy, I had my IR test with him last year and he was more than fair and reasonable. No real quirks, he just sits back and lets you get on with it, no nasty suprises.
As for the airports you go to, it all depends, I did my through CCAT and the school booked the slots for you test, so with some gentle encouragement ops would book the airfield of your choice for the exam.
If you are coming from elsewhere to do the test then I don't know who would book the slots for you.
Cheers, and good luck.
