Right on , Aussie. And it's a problem that's already been spotted and fixed, but keen eye none the less.
Quote:There are many historical sources which describe the sling's extraordinary performance characteristics. Its main competitor, the bow, had both a shorter range and slower rate of fire. Additionally, dozens of historical sources note the remarkable accuracy of a sling in trained hands. Although use of the weapon diminished after the fall of the Roman Empire, the weapon’s supremacy as the premier, personal, long-range weapon was not supplanted until the 15th century. Ultimately, changes in society, technology and military tactics rendered the sling ineffective in large-scale, organized warfare. The sling continues to be used in various smaller conflicts and by enthusiasts to this day.
