any Sonny D uke players...

just wondering what kind of strings you use or think sound best for this make....Mahalos!

So far I have only used Ko'oalau strings. They sound pretty good to me. the previous strings were probably the original strings the uke came with from Sonny D. I did notice initially that there was more string tension with the Ko'olau strings. I have a really old Sonny D that is probably about 20 years old.
