I have a short neck. The chinrest that came with my Fiddlershop Concert Violin felt too high with my Fiddlershop shoulder rest. I tried replacing the shoulder rest with a sponge pad, and that helped some, but still wasn't right. I purchased a Conrad Gotz Ebony Chinrest ZK256 and the fit is excellent. With my Fiddlershop shoulder rest, I feel my violin is now fitted especially for me.
