Comments: i know for a fact that the 2nd pitch(the big roof) goes free at wild 5.11ish hand jams. and ive heard the 3rd pitch goes free at hard 5.11 or 5.12.
pitch 1 and 2 can be linked with a 60m rope(or less) but can cause quite the rope drag.
also, you can rap off the top of the roof pitch(the 2nd pitch) with one 60m rope(just barely).
