Have you overcome your fear?
I actually thought this section of the fells was pretty awesome. That said, I did modify the course to avoid a section of greenbriar on the leg from 1-2, but the point is the greenbriar is totally avoidable.
I ran into a patch or two when I didn't have my head up. I did find that the medium green around #5 was perfectly passable, which was a pleasant surprise - no spiky things!
I agree, this may be some of the nicest bits of woods in the Fells.
