I have a daughter that is pretty small, at about 5' 2" (14 years old) and about 105#. She currently has a SQ Libra that is a bit worn... Looking to get her a BP/wing set-up... My question is: how does a full-sized BP fit on a frame that is so small? I guess I could let her try mine; but I would love some input from all you petite little divers out there...
