I’m using D’Addario Heliccore strings on my Tia Bruna fiddle. I’m not sure what I’d use if it were a violin, but I want to try Pirastro Tonicas, Obligatos and Evah Pirazzis. I’m sure at least one of them would be the ticket. Dominants came on my Tia Bruna and I didn’t really care for them, they do sound wonderful on my cheap Chinese Christina violin though. Go figure!
