Firstly I had Wolf, but got back problems as well...then I went to a violin builder and tried many alternative marques, the result was KUN after I tried a KUN several month which my violin teacher borrowed to me.

One thing I don't like with KUN: It is not that flexible than I want it to be. Wolf you could really bend, but I have problems with KUN to do it, I dunno, maybe I am inable...some future plans for shoulder rests might be bigger shoulder rests. I think they are too small in size. If you have it much bigger in length and weidth, and if it is made by more soft material, you might have less pains caused by shoulder rests, but that will be special made shoulder rests done for every violinist individually....(if this shoulder rests exists yet, tell me, I must try it..)

So far my dream of a shoulder rest.
