I gave my cello bow to my dad, and I got sceared b/c he looked like he wanted to smack me in the back of the head for being so slow. But I dont need a new bow, the bow isn't broken the hairs are the only thing popping. And I knew that, but it didn't know the hairs could be replaced. So he ordered me some good hairs from this Italian shop. :) I'm happy now
I doubt that are many, if any specific brands left anymore that have proprietary features or charachtetistics. My advice is to consult a music store or better yet a music teacher and find out what is availiable that others are using and satisfied with.
