Silver Head Shell Leads

I have an Audio Technica 33 Mono Anniversary cartridge and would like to replace the head shell leads. I'm currently using copper leads and am thinking about buying silver leads. Or for even more money, I could get Rhodium plated leads. What changes would I experience by trying silver or rhodium leads. Recommendations are always appreciated. The head shell I'm using is a modified silver plated head shell on a Thorens TP16 MK1 tonearm.
Thanks!
