Yep... in the flat country around these parts, it doesn't matter much if they run 50-100 yards... and if they are pointing in the right direction it can save you some work... on a pass through lung shot there is no fear of loosing the animal, the demise is quick and painless, and there is very little damaged meat.
Having said that... there are definitely circumstances where you might want to anchor an animal in it tracks... a goat on a ledge or a bull standing on the shore of a fast moving river, for example. But for the most part, I would prefer a clean lung shot and let them run... greatest margin of error in achieving a clean, one-shot kill... a "bang flop" is not always desireable... even though it is always used in a suggested positive context...
JMO... I don't feel strongly about other choices.
