23->24 would be ok, better than my routeI guess. Even using the path in the middle would do. I don't think there is much differences, you just need to be fit :)
12-13, thats pretty long way around. I'd say it's a bit risky. It's so long way one would not win much even if it's good choice. But is straight is faster than it look (elephant tracks made by other orienteers) you may loose quite a bit by going around.
16-17 left is ok. I don't think there is much difference. I ran
similar leg there few years ago.
Right to #8 would do, climb in the beginnig but rest would be fast. To #7 right would be bad I think, but maybe I should have gone more traight in the beginning. I went quite long way around for just 2 contours. To #2 it might be possible to avoid one hill by going south. But you might end up taking same climb early on, so maybe my route was quite good after all.
#29 I just ran path all too long.
You don't know what the forest is like here? maybe you should make a visit to Helsinki one day.
