My Ohana sopranino has D'Addario J65 strings, tuned to an E flat 6th chord (fourth string tuned to B flat, third string to E flat, second to G, first to C). I just tuned up the strings until they sounded nice. Those were the nearest notes. It's sounding great.
I have a KoAloha Noah, as well as two Kala Pocket Ukes. (One acacia, one mahogany.) I use Worth light Clears exclusively, and I love them. I also keep C tuning on all of them, and I love that as well. I've tried tuning 'up' and it sounds like a bad Chipmunks album-only worse.
