Re: creating a wide arc
I've always wondered about comments on 'wide arc'. What is wide? the hands or the clubhead?
The hands will travel on roughly the same path on the way up and the way down. If a player manipulates the hands on the way up with a 'stretch or reach' motion then they are becoming disconnected and have to compensate on the way down. The clubhead will travel on a path that is wider on the way up than the way down simply because of shaft loading and flex.
I'm not convinced that a wider arc leads to more distance.
An inside takeaway is normally referred to the clubhead traveling too far around the body on the backswing - it will normally be too low to the ground too. You can bring your hands in with an 'inside takeaway' but this is a correct motion rather than a bad one. We're dealing with terminology here and inside takeaway has typically been used to identify a fault. Since the only fault is the clubhead coming too far inside and low too fast, then inside is clubhead and should almost guarantee a wide arc on the way down. Usually starting from the top.
(...like over the top; a bad thing)
