The hair takes rosin quite well, I had it playing in a matter of about 2 minutes. The horse hair is well combed and securely attached, a few hairs were lost from menu packaging it but aside from that, even with aggressive playing I have lost no additional hairs.
The arch is perfect, the balance is also perfect. It’s extremely lightweight but produced a rich, vibrant sound. Furthermore, it’s carbon fiber so it will not be affected by heat or humidity and it is actually much stronger than most wood bows, making it very durable.
This is the highest quality bow I have owned, yet it is probably the cheapest. I absolutely love it.
