First attempt I was 2off, so some attention needs to be paid to the route. I really didn't want to do it again but it's not completely tedious due to the straight runs
I don't think it's such a bad level. It does take some thought to do it right, at 939. Because it's so long, it's not very nice, when you have to do it all over again, if you fail.
I failed more than once, lol. :)))
