A green, or Nitro Lime, set is settling on my (pink, plastic soprano) Ukulelia right now. They look great---like a stem for the flower on the uke's headstock---and are sounding sweet.
Difficult to compare them to other strings, since I've only tried a couple string sets on Ukulelia so far. The Auroras definitely sound better than the original clear nylon strings---more brightness and clarity. The Auroras have less tension and volume than the South Coast Medium set they replaced, which is a good thing on Ukulelia.
If either Lani or Duke could use a little color, you should try these out.
