midwest, I know that you can really get some junk strings, depending where you get them. Interesting that you have no vibration from your WC`s. Glad they are working good for you. I would try some firsthand, but I am too tight to buy something that I can make. I am funny that way. I don`t have a problem getting 2 or 3 bows a year, but I refuse to pay for premade strings. Anyway, thanks for your input on the WC`s.
