I bought a pair of DC 13.4S (stereo) with the undercut gel pads. They are really comfy (longest flight for me was about 3 hours, and I didn't notice they were on my head), but there seems to be a bunch of people who find DCs uncomfortable... not sure why, maybe they have bigger noggins? I would suggest if your club DCs are comfy but you want your own pair, get DCs, otherwise look at Lightspeed Zulus. I think they offer better value for money than the A20s. The only problem with non-DC headsets, is that walking through the terminal without those lime green DCs, nobody will realise you are a pilot ;-)
