Sir <salute> - - 
Are you still looking for an allied opponent?  If so I am willing to engage you on the field of honor.  I also have Marengo, so a match from that campaign would be fine.  For "Optional Rules" I agree with all of your suggestions, but would prefer "No Detached Melee" turned OFF; however I am willing to let you decide on that feature.  
Might I suggest scenario 005. "Montenotte HTH".  It is relatively small and I have not played it yet, so it is new to me as well.  However let me know if you would prefer another scenario...
If you are still up for a game, please send a courier with the files to:
