I use a DC H20-10 and I'm very happy with them. The gel earseals are very comfy and the gel headband makes up for the weight. I had a 2 hr flight yesterday and I didn't get that two-sink-plungers-on-the-ears feeling (and it was bl**dy hot!).
One thing I'd suggest you consider is mic compatibility. The M-7 electret mic is not always compatible with M-4 mics (available on others like the H10-40) although I believe the com box can have an influence here.
Anyway, happy birthday and good luck with the CPL.
