Woo Hoo ! 32 years later, time to retire the german bow purchased from a teacher.The luthier had a few models of JT , Coda and some wood models in the price range. Three basses in the shop , including my loud nasal blockless ply brought in for a soundpost tweak. Hadn't really considered the Arcus before but its response was clearly a big step up from the others. A little lighter - 120g , very responsive and much less prone to squawking . Thumb position was smoother and easier to get an even tone , and thus easier to move toward the bridge . Maybe it was the black hair ;-) .
