Fodera strings are Round Core (stainless & nickel)
Dean Markley Super Rounds are Round Core (stainless & NickeL)
Thomastik-Infeld Jazz Rounds / Jazz Flats are Round Core (pure nickel)
and well that is basically it...
It's easier / faster to use Hex wire for making strings.
Huh, I didn't know the DM Super Rounds were round core. Those are what I used before switching to DRs (first Fat Beams, and now Neons). The DRs are a lot lower tension, than the DMs, so I assumed the DMs were hex core. Interesting.
