I mdiator the Discoveries (s) Dugain, there are about 6 months and I can not do without, it is clear: an APRS PERIOD adaptation of a few days essentially the volume of the machine, the lance is closed forever. I do not add nothing to the pleasure of using this kind of tool. For cons, I do not know how to keep a Dugain 4 years! I tried three diffrent Contents, buffalo horn, wood (I do not remember which) and bone and I uss all three in six months. Of course, I practice two hours a day, but I work allger my right hand as much as possible (feeling hummingbird). It is clear, the more mdiator is soft, the more enjoyable to play (I think), the more it wears out quickly. The strongest I've tried is made of bone (no luck because it is the one I like least). 10 nanmoins no doubt.
