I agree with Matt's general point. I generally decline to "force" a player to shape a shot with trees, understanding that even very good players have difficulty working the ball both ways. I think it's okay for a tree to prevent a straight ball from getting into an advantageous position, but I don't think it's okay to go so far that a guy who always hits a fade will probably hit the tree and make a triple bogey.
Rob: At Cape Kidnappers there are a couple of holes where the players are rewarded for working the ball off the tee ... most notably the tee shot on #14 where you are playing diagonally across the ravine from left to right, and you want to hug the right side as much as you can. That hole gave a couple of guys fits last year, although they hit out-of-this-world second shots to make up for it. However, the fingers of land on which the course is built are quite straight away, so on holes like 15 and 17 there was really no opportunity to make them work the ball one way or another.
