I'd never thought the S6 should suit my old violin so perfectly. When I purchased the bow I meant to use it as a backup only, but now I play the Arcus all the time. I'm impressed how easily, precise, exact and differentiated it responses and reacts.
It appears the bow always knows exactly what I'm asking of it and want it to do. Long rehearsals and concerts can thus be performed without any problems but with great ease and joy.
