My main climbing partner in the way back was a soaking wet 125#. She had to strap into the anchors on the floor so she didn't get yanked into oblivion. Much amusement was had the first time she tried to belay (against my suggestion).i haven't been climbing consistently enough lately to be at the level to take the lead climbing course at my gym. our gym requires you to be able to climb every 5.9 route in the gym to take it, plus you have to have your own rope for lead.
