There are as many strings as answers. Personal preference is what is all comes down to. Pick up a set of Worth's (Clear and Browns), Living Waters, Savarez and Ph.D's and you can start having fun experimenting. Then you have Fremont's, Southcoasts, and another half dozen manufactures...and those strings you got, oh and Ko'olau strings too. I have tried almost all the strings out there except Southcoasts. For Low G, on some of my ukes I prefer a wound and others unwound...it's all about the sound you want to get and like on your uke. Some strings are very close in sound (fluorocarbons). I find the Living Waters and Savarez to be very close in sound on several of my ukes. Also the Living Waters and Worth Clears are pretty close. I think the LW chimes a bit more but it must be because those strings are made in heaven according to Ken ;-)
Good luck and enjoy your new uke!
