How can you tell if your swing plane is too steep or low for a particular club? I sometimes struggle with the concept of swing plane and how it changes for each club (steeper for shorter irons and lower for long irons?). The way I think of it in my head is that you need to utilise arcs for long irons so you can generate enough speed and get the ball in the air. With short iron you can afford to swing steeper (which compresses the ball more?) and trust in the loft of the club to get it in the air. With a long iron you would risk chunking a steep swing and with a short iron you would risk thinning a shot when rotating too much?
