During this past winter, the #1 ukulele string on my Pono tenor suddenly broke without any reason. I figure it was too cold in our basement [~67F] and the string just contracted too much. This is quite surprising because I've left my ukulele in the basement the previous year but the strings held true. The difference was that I was using Ko'olau Gold tenor strings during the previous year. I just switched to the Aquila nylgut strings last year.
Anyway, this gave me the opportunity to try out some Worth CT strings which were highly recommended in the ukulele forums that I've been in. I was able to snag a set of clear strings from eBay for ~$17 including shipping. The set consists of 63" lengths for each string. Hence, you're actually paying for 2 sets of strings. The price then is almost the same as what I spent for the Aquila nylgut strings.
The Worth strings are thinner than the Ko'olau Gold and Aquila nylgut strings. While the Ko'olau Gold had volume and the Aquila nylgut was crisp, the Worth CT was more mellow. It did not quite have the volume as the other two, however, the sound is very polished. They're also easier on the fingers and I recommend these strings for beginners.
Overall, I like these strings and I will stick to them for now ... until they snap again next winter.
