Discus 2b cockpit comfort?

I've never flown in a Discus 2b but have fantasized about getting one
someday. I do have a dozen or so flights in the font seat of a Duo
Discus and while it's a *great* ship to fly, it doesn't have as much
room in the front as our club's DG-1000 does (need room for keeping
stuff during the flight) and the seating is a little bit less
comfortable. For local flights it's probably not a big deal, but for
longer ones it may matter.

Anyway, can anyone comment on the relative space and comfort of a Discus
2b (or Ventus 2b--I'm told they're virtually the same) compared to a Duo
Discus?

Actually, a comparison between the Discus 2b and any of the following
would be helpful:

- DG-1000
- Pegasus 101A
- Grob 103 (yeah, it's huge)

I have enough flights in any of them to make the comparison meaningful.
If it helps, I'm pretty comfortable in the Pegasus and I'm
approximately 5'11" and 205 (hopefully decreasing).

Thanks,

Jeremy
