The differences in options between narrow fairway/tree lined hoes and open, freedom filled holes, are that the narrow tree lined hole's options are invariably dictated by the designer, or the maintenance staff, versus, having the option to choose your own line, your own shape, your own distance. Knowing what to do is only the booby prize. You still have to do it, and deal with what you've done. Nothing gets my goat more than having a narrow tree lined hole, where the rough is grown up in front of the green. Removing the ability to hit a low running shot into the green when one does find their ball under a tree, where the golfer needs to hit a low running shot.
Andy, That comment about center line hazards is interesting. It's contrary to the accepted, where centerline obstacles give the player at least four distinct choices to make. Right, left, short, or, long. The fact that you find them easy, is not, and should not be a ding to a hole. That choice that you make, to aim at it, and, know you won't hit it, is another option, too. The exact same mindset works with trees that are placed on one's line, or on one's shot shape line.
