For Curt's main Ko'olau CS Tenors (2009, 2017), which there are two of and both are C Tuning with a Low G. Thomastik-Infeld—Classic-N Strings—These are the custom set of strings that I use for both of my Ko'olau CS Tenor ukuleles and come from two different Thomastik-Infeld classical guitar sets. They are also available through our family Funky Frets Music Store and right here on LearningUkulele.com.
The flatwound string four and three last a long, long time compared to wound-round strings. There is a nice balance across the entire set. I (Curt) never used a wound string three until this set.
NOTE: This string set WILL work on a Baritone Ukulele and G Tuning (D G B E).
