I've been playing disc golf for several years and have experimented with an overhand (or tomahawk) shot for several years. However, the shot has always been inconsistent for me. It always gets the required height, but rarely achieves the distance I want on it. I know that there is a way to get it to turn over (so that the disc is flying upside down) and I occasionally achieve this, but I cannot do it consistently.
What is the technique for achieving this shot? Are certain discs better at achieving the turnover than others?
