I've experienced much to much of a breakage problem with the Elixer g string and have sworn them off forever. My new favorites are Dean Markley Alchemy strings - still working on which I prefer, the bronze or phos.

I usually save the box and write the date installed, initial impression of sound, then the date when they are replaced, and thoughts upon replacement. I take pleasure in the search for the perfect string. Experimenting with different brands and gauges is part of the fun.
I buy most of my strings from the below site. Great prices, monthly specials, great service, fast shipping (free on orders over $35). Check out the Sound Room to hear the tone of various brands and makes.
