I just wanted to share my experience the other day of trying out shoulder rests for two hours. As I am aware the journey for the best setup for you is daunting, I feel I got pretty lucky. I tried everest, kun, wolf secundo which I bought to try for a bit. I also tried the Mach one? I think its called? have a long neck and tension, so I also tried the Bon Musica. I thought they were all prety uncomfortable. The winner I found was the Comford Shoulder cradle. It is pricey at 65$ and it either works for you or not. The comford cradle is not adjustable and comes in medium and tall. The way it attaches makes it to were it never falls off. If you dont like wolf or kun and have a tall neck like me, give the Comford cradle a try.
