Wittner Hypoallergenic Plastic Viola Chinrest - Center Mounted

I like the Wittner chin rests very much indeed. I use the center version on my viola and violin. They seem to be very ergonomic and well engineered. I like the rounded tapered clamps. They are very easy to install with the included screwdriver, just be sure to have the clamps fully seated in the rest proper. It is quite light and gives very good clearance for the tailpiece. I wish they would make a hybrid version with boxwood or ebony, but barring that this is pretty great.
