I'm at the high school level and have been playing as much as I can ever since I've picked up the game. I'm not saying I'm good enough to need to master an unnecessary shot, but if I could pull a tweener off in a match or even practice match... that would make me a legend since no one else on the team has ever done it either. So any advice guys on how to hit one? What set up I need? Any pointers are greatly appreciated!
