I tried several different sets on mine. Can't remember what they all were, but at the end of the day I had Worth Clears on it. They are by far my favorites.
I also have Aquila's on mine (high G), which I actually got of my Ohana (they where factury delivered on that one, but I prefer Martins for that Uke) so I'm not really sure which ones they are. Before that I had D'Addario T2's on it. I like the Aquila's much better on the Les Paul then the D'Addario's.
