I do fingerstyle and some strumming.
I have Living Waters on my KoAloha Opio soprano and it is the sound I was looking for in my uke. Great for fingerpicking. I get mine from Uke Republic.
Martin M600 gets me the sound I want on my other sopranos - Martin, Brueko, Kala. My local music stores carry those.
A third choice I have been using on my vintage sopranos is D'Addario Titanium. They work quite well. I get them from Walmart.com. Free shipping with a $35 order, (I get a lot of stuff online from them anyway as I live out in the country, and that saves me a trip into town). I use the soprano size, but here is the concert. The price is right for trying out to see if it is the sound that you want.
