In reply to KeithAlexander: I´m not up in Lofoten til the end of july so cant help with partners.
However. My experience of british grades are limited but unless I´m way off the mark you can def. aim higher than grade 5 (more like n6 if yoú are climbing E1 back in the UK). Lofoten grades seems to be a little bit on the soft side, at least compared to the swedish westcoast.
But of course, you should still climb Only Bilberries.
