This issue has been long overdue and needed fixing. Milna was set up a long time ago, but the original grades have always been really off. Nobody really bothered to change the grades, but everybody was complaining about how misguiding they were. Anyway, the long awaited upgrade (or rather downgrade) of the grades is now proposed in our guide for your comments and use. I would like to thank to everybody who sent updates on Milna grades, especially Tomáš Homolka who gave me the final push.
The new grades have been proposed on the HvarClimbing.com guide, so take a look.
