Thanks for the info Matt! I imagine there is a fair bit of trial and error involved with EP's.
To answer your questions (for arguments sake!):
1. No, I don't observe with glasses
2. AFOV in my Orion Edge-On is 55' which I find very comfortable
3. I use an 8" Dob (F6-ish)
4. Sky conditions are usually fairly good (only just dark enough to pick up the Sombraro Galaxy for example)
5. I'd observe most weeks where there is good weather
Well....there you have it...!
