Metal spiral core, chrome wound.
Hi-tech, top grade, spiral steel core strings. Spirocore strings have a flexible spiral steel core. This core has greater elasticity than that of conventional strings, which means less inertia and a higher propensity to musical vibration.
All strings are ball end, full size, medium tension unless specified.

Pros: They have good volume and projection. Stable and staying in tune, responsive. A warm, full sound.
Cons: They were a bit harsh and metallic at first - similar to dominants in that regard, The main downside was the A string, which was awful. Very floppy. Occasionally sounded ok, with great care in bowing, but often sounded nasal, out of tune, or didn't sound at all. I replaced it with a Helicore A, which suited the other strings fine.
Other: Expensive for what they are. I think I'll go with chrome wound Spirocores or Prims when they need replacing.
Great quality strings for many styles of music.
Pros: Very good construction quality, they play & stay in good tune in a variety of environments including outdoor. From my experience they last a decent amount of time before losing their tone.
Cons: Not really a con, but they are quite expensive. You get what you pay for I guess.
