Thank you everyone! I am really grateful for all your feedback. You all helped me to make up your mind and I guess I will go with a moonlight setup again. Since I am also shooting LF, the 1000W or more are definitely becoming a factor. Also it seems that my original question can be answered that there is no real different in what the light does to the subject for b/w portraits on film. So I guess I will go out hunting for a nice 3 light setup again. Thank you all!
