Linear,
I viewed this in slow motion and I like the set up and the throwing motion. I just can't see many catchers being able to catch and pivot on the back foot and throw. The angle to the right with the body I wouldn't teach either, in baseball at least. I appreciate you taking the time to do this though. It might work with where you receive this pitch though. I'm going to try it myself. I don't play softball but are leadoffs allowed ? What is the distance of your throw ? I know you'll receive the ball quicker since the mound is shorter.
