Joe,
Every site is different. That said, my general rules of thumb....Forced carries are better (more tolerable?) if:
Off the tee than on the approach
On par 3's tee shot over a par 4 and 5 holes tee shot
On a shorter approach than a longer approach (even on par 3 holes, and I have arranged routings for the par 3's to be the holes that carry shots appear on.
On optional tee shots vs. required tee shots (i.e., alternate, short cut fw)
On an approach shot to a par 5 over an approach shot to a par 4 (i.e., allowing layup to about 100 yards)
Sandy waste over rough, if rough over natives, if natives over water.
Under 200 yards back tees, graduating down to no more than 2/3 of expected drive distance from other tees.
If a wetlands with cat tails, etc., with a tee built up high enough to carry those vs. a tee at grade where they may interfere.
