I found this on youtube and by far its the closest way I ever seen someone do a propper pendulum cast its the most perfect angle I have ever seen the propper swing.
Not sure really how far im casting I posted something here before about trying not to cast over the fish in future.
I havent been using tuned reels etc in a few years and a bit rusty so dont think I can cast as far as him but im sure with the right set up id get close enough
