** non travel agent opinion **
Probably becuase their are less variables (styles?) to abseiling.. when run by instructors or in groupos i guess a lot less COULD go wrong...
id imagine the PDS' from the companies would be a novel as they would have to specify lead, top rope, single or multi pitch, trad or sport or mixed, ice or aid, big wall, leader or second, what is considered "a rope", what constitutes a pitch or route, party of more than two, helmet no helmet, type of harness, age of harness etc etc etc |
