Wound C string tenor>>?

Does anyone know what they mean when they say "wound" C string...i'm looking at some aquilas for my soon to be kala...but i was wondering its not like nickel wound correct? its like nyglut wound around the felt string material? anyone know what this does for sound...or your fingers thanks!!

The wound strings I have used were some type of metal around what I was told to be silk core.
Think of Classical Guitar strings, that is what I use for Low G.
The wound string will squeek like Guitar strings do when you slide your fingers, seems some string makers use them so the C string isn't as FAT.
The wound strings will drone on long after the other strings quit making sound.

I only will use wound with a Low G strung Uke (you need it so the string isn't sloppy loose), I did play a Tenor the other day that had wound Low G and High C strings and it wasn't to bad.

my 2 cents...

I HATE the wound C string! Uggh. Its ok for finger-picking but for strumming, the only way I can describe it is "whispy". No sir, I don't like it, not one bit.

thanks guys!
