What is the difference between Arc and Angle of Approach? Thanks.

Thats one heck of a first question. Very few people could answer this fully and it would take them a lot of time to explain.

The short answer is that most hitters and all swingers employ the arc .....the curved club head visual blur associated with on plane club shaft travel . Sorta like the putting arc deal. The shaft rides the plane , the head rides an arc at the same time. Weird as that sounds.
