That spot can be terrible pain for the collarbone!
My SureRest isn't as high as my other rests, but I love that it covers that nasty spot. Read they're in the process of producing one for Violas - makes me happy, because I've been thinking about a 5 string Viola! ...after I play my Mortimer a bit better. (lol)
Don't know why I didn't think of it before, but Dr. Scholls used to have little sheets of adhesive-backed white foam and "moleskin", in almost every drugstore. The white foam was very dense and much thicker than the moleskin. I used cut out shapes to help train my Great Dane puppies' ears to stand.

@JohnG hey, finding what works & makes playing comfortable is important. I use a cosmetic sponge rubberbanded to my shoulder rest to make it feel right.
I got this cloth from a lady who handmakes them on Etsy.com. It slips onto the chinrest, comes down over the button, & attaches underneath by a small elastic band. Fits securely. I don't use it often, but I used it when I played outside in warmer weather a few times.
