I guess it would depend on the individual circumstances of each job. Giving tours in a R44 in an area that is flat with no weather issues is different than flying tours in Alaska or Hawaii. As a CFI will u be teaching new students? Advanced students? I was teaching touchdown autos back in the day in a R22a model(no tip weights). Transitioning to a 206 was a cakewalk after that. For me that was much better than flying around in circles all day.
