This strings are tremendous! I bought cheap Chinese baritone Ukulele (one with lot of good feedback though). I just made custom bone saddle (little than 2 mm at 12th fret height). And the nut was modified little bit to acomodate the GCEA tuning (deep & widen 2nd & 3rd fret slot a little bit). And after final setiing this strings the cheap Chinese baritone Uke converted to tremendous beauty! If you ever tried baritone tuned GCEA you'l never return to small body size :) Just the power of the sound and all that sustain. If you have beritone just try this set and you'll be ecited.
The strings sound good. Very similar to the Tenor Nylgut series. I managed to break one string(A string) when i was tuning it. The string didn't stretch properly after the first day. Go gentle with them while they are still new.
