I've been using the Royal Classics Recital guitar strings for about 4 months. I absolutely love them. These strings give my guitar a beautifully rounded sound.
But these strings do have their down side. The G-string is a little tinny when open (though it sounds fine when fingered). The strings are more sensitive to the weather than the D'Addario. With the D'Addarios, I only had to retune the strings daily for the first couple of weeks. After that, they stabilized. I've been using the Royal Classics for several months now and I still have to retune them almost daily.
Also lately, I've been playing several songs with drop D tuning. Going back and forth between the D and E tuning makes the sixth string lose it's tune even more often. But it's worth it to get the beautiful sound.
