I could have written this in a review, but thought it could generate some discussion here. I've just switched to Galli green pack silk and steel strings (GSL10s) and they are amazing. After going through about a thousand packs of Argies over the last few years, I can't believe how hard wearing the Galli's are, how long the tone stays good, and how well they resist breaking.
I play a lot, and play hard, and used to go through a pack of Argies a week, plus at least one extra single D, one G, and one other random string, sometimes more. Now, though I still change strings every week, I rarely break them.
Also, they do sound "broken in" right away, like people say, so I don't have to play for a few hours before the harshness subsides.
Anyway, they've been great - a real revelation - and look like they'll save me quite a bit of money on extra strings.
The other ones (GSBs) were - for me at least - pretty bad by comparison, and barbed up and became horrible to play after 3 or 4 days.
