another vote for the DC 13.4's
Was using the schools Sennheisers but didn't like them due to my big ears... The 13.4's fit my big lugs nice, and despite having a large head, I don't find them too tight as some people say. Plus, if you want to upgrade them to ANR later you can, by using the kit from anrworks.com - which is what I'll do If I fly anything noisier.
