I'm having difficulty achieving the 'spiccato' sound at sufficient speed, and am looking for tips on the bowing technique that will help me with this. Part of the problem is that my bow is not of very high quality, and is somewhat less 'springy' or 'jumpy' than most. How should I hold and manipulate my bow to better achieve the fast spiccato seen in the video I linked?
