Just curious what most people think about different methods of long-tossing. The Jaeger program likes to "arc" when going max distance, then throw on a line while in the "pull-down" phase (coming in). The opposite spectrum: I've also heard plenty of other pitching coaches say to throw long toss on a line (no arc) at all times.
So, which is right or the best and most beneficial way of long-toss, and what experiences do you have using either of the methods? Does "arcing" really promote bad mechanics? Is either better for the shoulder over the other? Which is more likely to get more velocity? More endurance? Better for overall arm health?
