A Seperate Reality, 5.12, Yosemite Valley, Rob, 1990

 An overhanging hand crack leading out to the lip of a 30' roof, 800' off the deck.   If you stop to place pro you tend to cramp and tire which makes a fall more likely but less severe.  If you don't stop to place pro your strength is preserved and a fall is less likely but potentially disasterous.  Not an uncommon dilema.
