Consistency is the Key
Unlike most sports which there is typically a defined right way and wrong way to achieve results. Horseshoes is a game where any number of different techniques such as swings, grips, heights, speeds can all still achieve the same ultimate response, the perfect ringer. Now I am not saying some styles are better than others and some people should go back to the drawing board but the main key to pitching ringers is to be able to repeat the same motion time after time. My experience with this in the past is the times in my career where I accepted my style for what it was and only worked on perfecting that delivery time after time I had good results but any time I tinkered too much and tried to change things too much my consistency and average suffered. Find a swing/ style that works for you then just keep practicing it until it becomes as natural as walking.
