In your most recent article in Disc Golfer, you mentioned places where a throw off the fairway leaves no room for a recovery shot, but forces the player to pitch out to the fairway. I've seen criticisms of the pitch out in other forums as well.
Admittedly, the pitch-out throw isn't usually much of a golf throw. Unless you throw as badly as I do and sometimes just reaching the fairway is a challenge. But it seems to me that these areas play much like O.B.---a serious hazard that you seriously want to avoid because of the extra stroke it will cost you. Other than the fact that it's harder to fly over, how much different is a fairway lined with dense rough that will require a pitchout from a fairway lined with O.B.?
That's a very important question, David.
As you mention, the flyover aspect can be critical. Imagine for example, that the USDGC course had tall trees everywhere instead of yellow rope -- it would play very differently. And you're right about the psychology of wanting to avoid a certain area.
We actually started to discuss this topic a little earlier in this thread. If you go back to October, mubhcaeb78 asked about his course, where going into the thick stuff can require multiple shots just to get back to the fairway. In that case, throwing into the rough can actually be worse than going OB -- an overly severe price to pay, in my opinion.
Probably the biggest difference between pitching out and OB, other than having to execute the pitch itself, is where your next lie is. Imagine, for example, that your drive heads into the woods short of a dogleg. In an OB situation, you might take a lie in the fairway and have to pitch up to the dogleg. Now you're lying three.
If there's no OB, you might be able to pitch "forward" a little and get around the corner. Now you're closer to the pin and lying 2. In that case, being in the woods costs substantially less than OB would have.
What I'm lobbying for in my article, for those you haven't read it, is a type of fairway that's not as black and white as "in the woods" or OB. Instead, there are a range of rewards and punishments, and players who just miss the fairway, instead of being completely screwed, have a chance to make a real recovery shot, not just a pitch out.
The fairway feature I describe in the article is called a PITTSBORO, which stands for Place Improving The Throwing Strategy By Offering Recovery Opportunities. Such features are not generally easy to create, but they can really enhance the playing experience, and I'm hoping that the state of the art in course design will now head that way.
