I did a very similar route to yours in 2018 with 3 friends. Had perfect 25+ degree weather all week. I'm going back this summer 2020 two up with my partner and a few friends up to the Artic Circle centre. I loved riding there so much and can't wait to go back and experience even more with my partner on the back. It really is such a beautiful country and I often think about it. Loved your report.
