I really didn't need it in Argentina, Tamid, and haven't had the need since. I still have it, and if I ever have shoulder problems I will do as you suggested. Thick padding of any type is disconcerting to me. I put on a pullover shirt a couple weeks ago that was given to me, that has a very thick padded area over the shoulder, and tried it on a sporting clays course with my big P gun. I had to pull it off after the first three stations. Anything that different is distracting to me.
I think I'm getting "old and set in my ways".
