DCs for me too, I've a 13.4 and a couple of 10-40s.
I love the 13.4s but they don't feel quite as sturdy as the 10-40s, having said that...I always grab the 13.4s for myself and make others wear the '40s.
The big thing that made them comfy for me was gel ear seals. I loved them the moment I tried them on...sitting at home putting them on with the TV on marvelling how quiet the world went.
Ok..I need to get out more.
