That was my original thought, and this thread has convinced me that it's the right choice.
My biggest challenge is that I don't have a primary stoker, but several and they're all different:
5'0 (and growing)
5'4
5'10
5'11 (and growing) - might get only one season on the new tandem
Thanks to all who replied to my question.
