Since this is now a new old thread, I'll add my :2cents:
I have a new Kanile'a koa tenor that came high 4th g with Aquilas, for which I have little love for most of my ukes. I swapped out the high 4th Aquila for a low 4th G Fremont, and it doesn't intonate properly. It's right on at the first fret, then misses most of the other notes, basically going sharp. This uke is spot on up the neck, but not with this string. I modulated tension and distance from the fret and couldn't get it to play right on the note on more than a couple of frets.
EDIT: I adjusted the nut just a hair, which fixed the intonation problem, I was thinking the string was just old and worn, since it was fairly close to the note every 3rd fret or so, but still off. After that it was ok. I did put the clears on, do like them much better than the Aquilas (I noticed a string squeak on all of the Aquilas I hadn't heard before in the process) and like the Worths, they are less bright but are richer. The Aquilas are only a month old without much wear because my schedule has been hectic. I will say I wish the clears were white. Clear doesn't really look good on anything IMO. Black looks great against most colors and finishes. : Finish EDIT.
I just got the ebony bridge pins so will try Worth Clears. I really like the look of darker strings on this uke, I don't even mind one black string, but I had clears on my last tenor and found that those were the right strings for that one right before I sold it.
Other than that, I like the Fremonts I have on a soprano that carries them well. But if I had the choice of either I'd go with Worth Browns.
Hilos pretty much suck IMHO.
