Quote:I think underhand is a legitmate style. Perhaps underutilized but, having taught begginers, I've also seen rocks go straight up in the air so I can see why it isn't always used:
I know precisely what you mean. Five years ago I was teaching a fellow boy scout to sling before one of our meetings began. We were 150 feet away from the building where the meetings took place. Ammo was from a convenient black walnut tree (the only walnut tree in the area); the scout did a few relaxed rotations underhand, tensed up during the release and sent the walnut anywhere but forward. In the meantime, the scoutmaster walked out the building, heard a smack on the sheet metal roof, and a walnut falls and rolls at his feet.
Single rotation overhand is the way to go for beginners; kill a shoulder, save a window.
