Strings are totally subjective. My first ukes were Kalas, and they had Aquila Nylgut strings. When I played guitar years ago I had been used to steel strings, but I didn't like the sound or, more importantly, the feel of the Aquilas on my ukes. I did some string research and switched to the fluorocarbons. For me, they have a softer, more comfortable feel, and the sound was more dimensional and full. I've tried Martins, Worths, Oasis, Living Water, Romero, KoAloha, and Uke Logics, and Ko'Olau Ahos, off the top of my head. Except for the Ahos, I like them all a lot better than the Aquila Nyguts. As a beginner, you might just want to stick with what you have, until it's time for a string change. That'll give you time to concentrate on gettting a consistent sound, and actually learn how different playing techniques can alter the sound your uke produces. If you want to change them, nothing wrong with that either.
