My Lothar Seifert may be in need of recambering. I've had it for around ten years. Before that my teacher at the time owned it and before him, his former teacher owned it. I do not know whether it has ever been recambered. Even at the time that I bought it, the stick may have lost a bit of its springiness. So my question is whether any of you have recambered your professional grade bow, and if so, what were the results? Would you do it again? I am tempted to buy another bow, but I probably would not sell this one.
