Sometimes there is a tip I can share here or there that can make a big difference. Usually it is pretty easy to get a hang of the casting, but occasionally there is something I can point out that I might have not covered in our videos, forgive me if these may be a bit repetitive but here are things I may have not covered well on my videos or perhaps one of these will help:
– Tapered lines will be easier to cast than level lines. If you’ve been struggling and you are using a level line, please give a tapered tenkara line a try.
– The back cast is the most important thing. Focus on throwing the line back more than on throwing it forward, the rod will take care of shooting the line forward
– Make sure to stop your back cast with the rod pointed up (12 o’clock). Having an index finger on top helps with that
– Keep the casting light. I know you mentioned you try it, but sometimes when trying to correct casting people will try going stronger/more forcefully and that doesn’t help
– But, the casting is fast (for timing of the cast see my videos).
– Keep the arm close to your body and relaxed. You’ll use a combination of arm and wrist.
– You mentioned having the tippet pile up in front of you. In my experience, the main cause for that is keeping the grip very firm at the end of the cast. My suggestion here is when you move to your forward cast and stop your rod pointed roughly at a 45 degree angle in front of you, relax your hand. This one usually goes a long way. It is a light opening of your hand as you come to a stop on the forward cast.
