Pick one and start it up. I like playing blind too, and I usually play with all options on. The scenarios that I'm playing now that have not posted yet are The Hills of Olkhovatka (just started) and Panzer For!! (1/3rd of the way through). Other than that, you can check my scenario record or ask me first to make sure that I have not played it before. 2 turns a week should be alright for me.
