Cape Breton fiddlers Natalie MacMaster and Jerry Holland use Pirastro Chromcor strings. I tried them a year or so ago and am very happy with them. I order mine from Shar Products;

Their toll free number is 1-800-248-7427. Don't get discouraged with your fiddling; stay after it. It'll come. Good luck!
