The second fairway plus some more trimming so there's maybe 10 feet clear outside the trees that define a tight fairway. BRP4 would be bit better if a few strategic trees were taken out on either side to allow challenging recovery shots and the right side was trimmed back a bit. Left side misses are much more forgiving for recovery attempts. The biggest issue with BRP4 is for tournament play where it backs up not just due to the tightness, but if 100 feet longer, it would allow more than one group to play it at a time.
