I'm playing both classical and jazz, so I need strings that do the job for arco as well as pizzicato-playing. This set was a sidestep from the thomastik spirocore strings I normally use, and I'm quite pleased with the result. In orchestral playing you have a nice rich sound, that blends nice into the group of players, and for pizzicato playing there is a nice 'punch' to the sound.
So for bass-players who are in the same situation as me I would recommend this strings.
