When you get in to bows like hybrid R/D (heavy on the reflex) and recurve, etc, you can throw a lighter (target) arrow pretty darn fast, or as Dean Torges would put it, "A snappy bow". For a real workhorse that throws a heavy hunting arrow, consistently, you can't beat a perfectly tillered flat bow 'type" with more of the limb working. It's really apples and oranges though. Depends on your taste. I guess that's why we build so many different types, and just shoot whichever one you fancy that day.
