I have a Prince O3 Hybrid Hornet(10.1 ounces strung, 2 pts Head Heavy), and I use PHT 16 strings strung at max recommended tension, and as you have read this is killer on my arm. I managed to take out the butt cap and I am about to add some fishing weights inside. How much do you think I should add so that my arm won't feel as much pain? Also the handle is completely hollow, thus should I fill it with cotton before I put in the weights? Any other suggestions are welcome. Thanks in advance.
