Kevin,
I agree with you that #3 needs a bit more tree clearing, but if I was prioritizing, #14 is the one that needs the most clearing. I would love to see the entire left side rid of trees. That makes the drive less penalizing, but still the optimal play is down the far right. It would create much more strategy and possibly make the hole harder, as playing up the left would leave nearly an impossible second shot to that green.
I am afraid with a much wider fairway, #3 would actually become significantly easier, because it's still only ~370 yards. I know the green is a monster, but if you're able to attack it with a wedge regardless of where you are in the fairway, it becomes much easier. With the trees down, it forces a decision between accuracy and length.
