Ok down in deepest Cornwall, we have no sport climbing and Carn Vellan as decreed by the BMC is now a trad crag.So suggestions of some sport grades for boulder traverses would be useful, save me driving to Ansteys 6c+ (7 metres) into 7b+ (8 metres) = French Sport7b+ into 7b+ (8 metres) = sport and boulder gradefound this http://www.hongkongclimbing.com/general/gradetables.html which is the first time I've seen a conversion for boulder traverses into sport grades.opinions anyone?
Add the two grades together add 4 then divide by 2. For instance Left wall traverse into the start of Rock atrocity is V11 (or it used to be) continued into the finish of RA is V12. 11+9+4/2=12 ta da. It seems to work with most link ups!
