We've had lots of discussions about strings and bridges. You can buy a set of Nylgut Minstrel strings from Elderly Instruments (among outer places) that will give you the correct sound. They play fairly well, and last forever.
I have had good luck with varnished gut strings. They last fairly well, and I far prefer playing them to nylon or nylgut. If you find the forum discussion Bridges and Strings here you will see some discussion on this.
