We prefer your more classic desingns please work out in this direction. In #12 we don´t like very much the red triangle, and maybe we would undefine somehow the bull so it remains in the logo but with less importance ( I don´t know if choosing another colour like grey maybe... ) # 9 could be a nice idea but we wolud chage the design instead of an acueduct maybe an old country house...
About the letter tipology try to choose some not to complicated..
