In reply to Max_01:
Thanks to all for the advice, I'm mad keen to get there now, and some of those longer routes might get seen on the second week!
On ropes, think I'm gonna get a Mammut Revolution, Edelrids always go twisty on me.
In case anyone searches on Kalymnos and finds this thread, a friend at my local wall told me (which reiterates what Max said above):
"You can't clip and thread the bolts on Kalymnos at the same time. Take a few old karabiners you're not bothered about leaving, and if you need to bail out on a route, clip the krab and lower off of that."
It hadn't crossed my mind, so I'm glad it'll be the 10 year old ones and not the new Spectres that get left if I wimp out!
