Here is a tip: It is not 10 & 2 anymore. Those numbers worked well cane and glass. For our newer space age graphite your numbers are 9 & 1. Graphite rods require a bit more force to load well.The 9 & 1 cast, which is also know as a wind cutter cast, puts more force into the casting stoke. You want to throw the line high behind you on the back cast and then push it down in front of you on the forward cast
Think of shaking hands; reach out as you do when you shake hand with rod in hand, and you will find your tip at 9 to 9:30 on the clock. Now with your wrist straight and you elbow touching your ribs bring your hand up (rod in hand) as you would when you answer the phone. In this position your rod tip should be at 1 on the clock face.
Don't bother trying to remember the numbers, you can get confused between where the rod tip should be and your hand should be. Focus on keeping your wrist straight, and your elbow down, while you answer the phone and shake hands.
Casting is easy with the right instructions.
