Yes, that's an interesting question with two answers: One for the pros, and one for the rest of us. Think of #11 at ANGC, new trees all the way down the right side since Tiger, seemingly because it got to the point where it did not matter if the pros fanned one over there in the old "first cut", they could nuke a 6 iron and stop it on that green. So they narrowed it to stop the bomb and gouge. For the rest of us, it used to be a hard shot, bad angle, with no spin, and now, the trees make it unplayable, a chip out, as if its a water hazard. So the trees have two different effects on two different games being played.
To me, a grove of trees that functions as a water hazard, with chip out being the only option, is bad. Give me a shot: Some low hook or cut or SOMETHING around less trees to try to get remotely back in position, that's where the fun is!
