I feel a longer walk is better than a bad hole, but if possible walks longer than 200 yards should be avoided as they break the rhythm of the round. It is simple you don't walk much longer than 250 yards before your next shot while playing a hole either, most people don't anyway, while shorter walks occur on a golf course all the time.
I find this interesting; I would much rather walk 100-200 yards a few times than 400 or 500 yards once, as it breaks up the round too much. Do other people have the same feeling?
If yes it would be better not too minimize green to tee yards, but to minimize the number of green to tee walks over 200 yards....I believe this to be the case.
