rules to play rock climbing

On slab or corner climbs get the climber to hold a tennis ball in each hand and then climb the route. This climbing game allows some use of hands for balance and a little pulling on massive jugs, but real success comes from the thighs. This can be run either as a skill developer on its own or as a wee competition. NOTE watch as some people will try and use finger tips to cheat and makes themselves prone to finger tweaks.
