In addition to full sets of either Versum, Versum Solo, or Spirocore strings, another popular option among cellists is to mix the Versum Solo A and D with the Spirocore Tungsten G and C. 

The Versum Solo offers strength and power for the upper strings while the Spirocore Tungsten lower strings enhance the volume and projection while maintaining warmth and clarity.
