What's more important on a tandem? in Instructors July 26, 2004 With the exception of 1 tandem I have had the Student flare on all. I think we can get more to return if they are into the whole experience. It also will help when my 175 lbs butt gets sadled with the 250 lbs reporter for a PR jump.An Instructors first concern is student safety. So, start being safe, first!!!
