My recommendation is to watch some Tom Clum videos or take his online video class regarding the the rotational draw.
I shot linear for over 30 years, switched to rotational after developing shoulder problems and watching some Tom Clum videos. After using the rotational draw for three months the draw shoulder problem went away. Also had issues with the left shoulder, changed it’s position when drawing and shooting after talking with Tom, that problem went away after six months.
I don't know how to describe what I do....Rotational or swing draw is probably accurate.
When I was leaning my draw shoulder forward.....and drawing straight back...it was impinging my rotator cuff.
If I keep my shoulders square and do more of a rotation using my back with little tension in my forearm, my shoulder doesn't hurt.Its like Arne Moe recommends on his vids but make sure your shoulder are back/square.
