I did some flying there a few months back. Admittedly it was just a dual check, but the guys there all seemed professional enough.
I think its a bit rough to say that you will always be a number at a big school. I used to instruct at a large school in WA, not in the game anymore, but still keep in contact with a number of my students. In fact I had lunch with one today. Don't just assume that if you go to a large school you will automatically be a number.
Have a look around and ask a few of the members/students there to get a real feel for the place.
