Here we go again. Anyway, at this point, Aquila is up 55%. The easy part about choosing Aquila is there is only one string. The bad part is there is only one string. For D'Addario, if you compare Aquila to D'Addario's "`ukulele" string set, then Aquila. If you compare it to D'Addario's ProArtes, then pretty much D'Addario. I say pretty much because from there, are you choosing the Clear Nylons, Black Nylons, Silver wound basses or the elusive Bronze basses, or even the T2 series composites? And, which tension, on which instrument?
Personally, D'Addario T2 Trebles with J4804 basses. Otherwise, like MGM and Craig, its Savarez Alliance 540 series.
