The first option that Robi talked about is the best short term solution, but it's going to do it again. One other thing that can help is when you store the spin pole, is to store the line in a figure eight insted of the typical "wrapping" it around your arm. I was doing this, but I still got twist in the line, but not as bad as you described. So, I went with the stripped core method. It it seems to be working out so far. I don't have to store it in a figure eight, I wrap it and throw it in the snuffer bag.
