Musicians and humans in general like to needlessly bash things they don't understand. In the case of halfrounds they never reach the same level of "dryness" in tone compared to the classic flat, and they never sound as harmonically rich as a classic round. But in between those two extremes lies a superb voicing that while not for everyone (clearly demonstrated by all the haters) is one that is inherently unique and very much it's own thing. The pure nickel wrapped offerings from Daddario require extensive aging to truly reach their full potential but once they get there, the warm fundamental was this mwah quality to it that almost approaches fretless territory on an fretted instrument all while doing away with minimizing the undesirable traits of really old rounds (inharmonics, clank, position change 'squeak') their halfround low B is exceptional when aged properly if you enjoy making use of higher fret positions on it, it growls without the nasty over tones of a roundwound low B while never devolving into flat out thump mud like a classic flatwound low B. A heavy nylon pick+halfrounds and you've got yourself an sonic weapon that sets you apart from the usual copy and paste blandness. I shouldn't be giving away my secret sauce, but I'm feeling exceptionally motivated by kindness these days.
