I'm looking at purchasing an EC folder for my husband to make his Aeronaut more usable for business travel. I know that a Tristar would probably be the better solution for business travel but he loves his Aeronaut and Cadet combo. Typically, it would be used for a pair of suit trousers and up to 3 business shirts. Lots of you seem to use the EC folders with your favorite TB bag but which sizes fit best? We have both an A30 and A45, so sizes that fit both would be useful. Thanks all!
