Not all wood holes are good holes! I would even say that BrotherDave's example is proof of this. I love technical courses, but if the average to good player's percentage of getting a decent throw out without hitting 5 trees is so low then the hole is pretty bad IMO.
Wooded holes should be playable without significant tree interference when you get off a great throw. ie - straight off in the direction of your release with minimal fade. If the pinball affect is set to trees every 4' apart then you are solely relying on luck!!! I don't care how good you are
I think luck is great, but a hole should never rely on luck being how par is acheived!
I think a hole can reward luck for a beginner or average player, but that upper tier players should never be relying on luck on a course. That's just my opinion.
I have no idea what an expert would say! It would be nice if one would chime in.
