Drop C (CGCF)
F#BEA (with a .175)
All very impressive, the 6 string sets especially have a more balanced tension than most manufacturers.
That .017 is listed for octave up G, which is very impressive if it really is a wound string, it's only listed as wound at Schneidermusik, not on the Pyramid catalogue where it is ambiguous. The .020 is listed as a light high C string.

Currently my 6 string bass is tuned in neutral thirds (3.5 semitones), i'm planning to order an all-wound baritone set 20 25 35 45 60 75.
