Don't think it is much harder but it's still hard for 7b+!

Definitely harder. Just need to contrast it with Hall of Mirrors. For ID to remain at 7b+ HoM would need to be downgraded to 7b as ID is now half a grade harder. However, because HoM seems to be straight 7c it would make sense to regrade ID to hard 7c possibly 7c+ IMHO.

Lewiz, with respect, I think your initial reaction just after you pulled the hold off was correct. You only thought it should remain at 7b+ after considerable practice. When I did it clean (after at least as many attempts as you) it felt like 6b+ I was so familiar with the moves and body positions!

I agree with Marcus, the move for tall people is seemingly impossible for shorties (at 182cm I can only just make it at full stretch, tried everything to get even a cm more hight but no luck) and the alternative shortie move is nails.
IMO v hard 7b+ people over 182cm and hard 7c otherwise.
Loved the route though, don't really enjoy that last crux now though... right at the end when you are ruined!
