I think there is a world of difference in doing the Slovak and the Moonflower, even if you go to the top of Hunter. To my mind the Slovak is a much, much bigger tick.
Giving overall grades to these sort of routes is fairly nonsensical.
To JCM: 90 degree ice means vertical ice. It makes sense to me as a grade.
