as was mentioned and you stated you really need to find a stance that works for you. I ride duck and love it. I have been messing with my angles to see if I can get a better stance. I ended up having pain with certain angles. So I slowly played with them and found one that felt a little better.
give it some time and try different angles till you find one that works for your riding/body
