I'm using them on my Ohana SK38 soprano, they are a joy, and by far they are the only strings I've used that are 100% intonated all along the fretboard.
with Aquila New Nylgut, Super Nylgut and GHS black nylon I always have some frets out of tune, some "zones" sharper (like the 5th-7th fret zone) or high notes.
I've noticed a curious thing, however: when I play with D'Addario Carbon, the overall volume seem quieter, and the sound slightly "dry", compared to Aquilas (in particular the SN, which are mellow).
then I record it, and WOW! the uke is louder and rich sounding, with the right amount of basses, making the Super Nylgut sound too dark and the New Nylgut too sparkly and scooped on the mids.
the thing I like the most, but I understand that it's a matter of fluorocarbon vs nylon/nylgut, is that they make the strumming sound clear, allowing every string to be heard clearly.
fingerpicked are a joy of hamronics and precise intonation.
the D'Addario are also well balanced in tension, string to string (I'm using the soprano/concert set, high G, but the gauge is the same for tenor high G set), and in sound/volume.
with Aquilas I always find the C too loud and howly.
they also stay in tune better AND are easier to tune with friction tuners.
last but not least, if mounted wisely, on a soprano (with the EJ99SC set) you can make two sets. it's just important to make the knot at the bridge without wasting lenght.
