A second Kiwaya? You have been on a shopping spree!
My only Kiwaya first-hand experience is the Famous FS-5G, and I really like that one. The playability is quite amazing, and it's super light. My other surprise was the aNueNue Moon Bird that came out of nowhere for me and that is wonderfully built and feather light, with huge projection that I only heard from KoAloha concerts before. I think it's good that more brands offer high quality ukes in the $700-1k range.
It's curious. When I started getting more serious about ukuleles, I was sure that the holy grail for me would be Hawaiian ukes. Now, a few years in, my two favorite ukes are not only not made of koa, but they also come from Australia and Taiwan/China.
I sold the Hawaiian ones (the KoAloha and the Kanile'a) that I had, but still would like to get at least one Hawaiian K brand uke again at some point.
