Airliners
Sometimes those 737's can be a problem - normally when they're occupying the runway waiting for a release from Birmingham, while I'm flying round in circles somewhere mid-downwind. . .
Having said that, learning at a field with full ATC is, I think, the best way to go. That way you get used to the control, and don't get scared / worried on your first trip into such a field later on.
Cheers,
David
