I did try a few places on the far side of the path. Most spots are 40-50% rough, but I managed to find a few spots on the edge with 30-40%.
When I putt at full power from there, at worst I end up in the middle of the rough between the path and the green, at best I dribble the ball onto the green maybe 10 yds and end up 50 yds short.
Couldn't find anywhere that did better than that.
I suspect it is all in finding the best starting point for your putt. But the camera angles and visibility back there is simply awful, so it is hard to work out where you are - let alone where to try next. Like I said - I gave it up after quite a lot of prospecting.
