going right on that control gives some extra climb. Also, you need to overrun quite a bit to get past the uncrossable fence. I can't remember which heat I was in, and I can't remember which way I went during the race either, but I think I more or less did what Thierry has marked on this map.
I think the climb is the same left or right, but that fence at the end does add enough to make it 'eh'. I guess an advantage is climbing at the beginning of the leg instead of the end, but you don't get to do most of it on the road.
