D'Addario EJ46C, Thomastik Classic CRK125 or Concertiste classical nylon strings;
Martin Silk'n'Steel for a lower tension feel with a traditional fingerpicking sound;
Ernie Ball Paradigms on electric or acoustic guitars (or Slinkys for less usual 'half' gauges unavailable in Paradigm range);
Ernie Ball or Martin mandolin strings.
