This case has been extremely handy for carrying both violin and viola for teaching, playing, etc. It is not too cumbersome. Two problems however: 1) no room for shoulder rests 2) viola side is non-adjustable - I had to make my own foam insert to make viola fit properly, otherwise it would have been loose enough in the case for viola scroll to swivel and hit side of violin. It would be great if foam inserts were available with case so smaller violas would fit properly. It would further help if there were separators between scroll of one instrument and body of the other to avoid contact.
