Kalium Strings. Hex or round core?

[Systolic]

Thinking about trying a set of Kaliums for Drop C tuning. I can't seem to figure out if they are hex or round core (stiffer or more supple,) as that will definitely be determining factor in the gauge choosing process.

Anybody know?

Kaliums are hex core......but, they make them in such a way that are much more flexible per gauge than most hex core strings.

Figures. So do they feel the same as round core or still a bit stiffer?

They feel great to me. I'm using a heavier guage than I usually do and they're pretty flexible. Great tone, feel and they last a really long time.
