"I have had 3 surgeries on my right shoulder all of which have been absolutely unsuccessful.
I was taught to use my arm by planting the upper arm on the side and using only the lower section of the arm and I cast out of a kayak. I can cast about 30 ft using that method, and "
A suggestion, use a Trout Spey or a Switch rod, then you will find its just as easy to cast with either hand or either shoulder and still cast over 60 feet with a little 5/6w 12footer.
Which will take the pressure of that problem shoulder.
Kind regards,
