G'day mate,
I personally use the Jeppesen Student Bag, it's seen me right through my career, not to big and not to small, seems to be very popular at my place of employment as well.
Jeppesen Student Pilot Bag - JS621212
If you do decide you want the Jeppesen Captain Bag, PM me as I initially brought it, but it was just to BIG so it's only been used a few times.
Happy Flying
