This may be true. I have some old ones, in 4 and 5 strength, and on my really great close-tip Florida STM they simply sing. Very "lively". Of course, they are each different within a box since they are cane inside... so that is a general statement. But the good ones have a great sound, at least from these old boxes.in my experience, and by direct comparison, they have suffered since being take over by D'Dario (am I spelling that right)? No matter what Dadarrio (I will keep trying different spellings; one will make sense) says, they are NOT the same.
