The sport version of Big Plum is bolted from the roof upwards,
finishing rightwards up the final section of The Spider. To make
it a full sport route use the bolted start of The Spider (long
draws required) However the rope drag may prove unbearable. The best option is to put ethics aside and have a super high pre-clipped runner ie top rope the origanal 1st pitch (VS) off the fixed gear in the roof.
Take care on the upper section - some loose
