Funny,drock shot winter leagues this year as a teamate of a level IV instructor that works with the olympics as well.He has shot in my yard and on the range with me and I can tell you he is still a slight bit short on the draw and also has a good grip.He is a big man and has a big frame and string oscillation can get anyone under the right circumstances.When you get behind your shot properly,you get closer to the string path and someone with big forearms may need to where an arm guard or utilize a string suppressor.BUT he doesn't need one.He just stated that sometimes he can feel the the string touch his skin.

Of course,you can shorten up.Open your stance,as well as shoulders to create more clearance but that creates more issues than it solves.
