In reply to chubbs2: on those two routes the threads will either be in, or not. If they're in (likely) they'll be in good condition. Some public spirited individual removed all the threads from BG a few years ago so any in situ will be quite new. Majolica doesn't rely on many threads anyway, more small bomber wires from memory.
Take some small threads in any case. Small wires most useful too.
Btw plenty of people will have been climbing there, it isn't really affected by rain and dries very quickly.
