I don't see how this can be the same grade as Kaabah. If evo-kaabah goes in at 8c+ then kaabah should be 8c, in which case mecca ext needs to go to 8b+ and mecca to 8b. It's got to be at least a grade harder than Progress surely (from my extensive 1 day trying Progress)? I talked to Steve about this sometime this year. I think we agreed that for evo-kaabah and for mecca extension it's the case that if the first part is at your limit then the whole thing will feel a grade harder, whereas if the first part isn't at your limit and you can do it 5 times in a day (!) then you might think they were both the same grade. Much like stamina routes always feel easy if they're below your limit. It was always on Steve's website routes list as 9a.
