In reply to johncoxmysteriously:
From the UKC report on Dura Dura FA:
...And Adam also explained why it is harder than The Change:
"If I compare it to Change I think La Dura Dura is harder, but still 9b+. Change really suits my style of climbing, the crux has some moves where you need to be really flexible and it seems to have been naturally made specifically for me. I know it might sound strange, but La Dura Dura has more straightforward climbing, but you really need to get everything wired 100%. I needed about 5 weeks for Change, and 9 weeks for La Dura Dura. I'd say that for me La Dura Dura is a better achievement because it fits my style less."
Thanks,
Jack
