I have daddario pro steels right now,
Note that D'addario string packs have really bad tension variance among strings - generally with the B being the lowest tension, and the D being high tension.
For example in the XL170-5:
G: 42.8 lbs
D: 51.3 lbs
A: 42.0 lbs
E: 36.5 lbs
B: 34.5 lbs
This can make the B seem really floppy and seems to effect it's ability to cut through relative to the other strings.
