NSIA carries all levels of wooden bows. The cheaper, Asian are tested to make sure that they are fine to use. We believe that we have sourced a great bow maker whose wooden bows are easy to tighten and loosen. Furthermore, these bows have a good strength and the right amount of spring. (In the past, we often noticed that Asian student bows have issues in those areas.)
Regarding German bows, we now carry (almost) the complete range of Doerfler bows for all string instruments.
