Initially I have had some trouble with the lightness of the bows. But now it works really well. It certainly takes a little time getting used to. I played the Arcus Sinfonia in our last concert and was surprised about its wonderful sound. Especially the A-string sounds much improved on my cello. Until now I always had to apply a lot of power to make the A-string sound, but these bows respond extremely well, even at the tip.
There is one more thing: lately I had pain in my right wrist, possibly due to too much cello playing. Well, they are gone, since I play with an Arcus bow. And I have had just as many rehearsals and concerts since."
