I use DR long life Red Devils (red strings) - i admit the reason why i bought them was because of the colour suits my guitar really well, but they are suprisingly nice strings which supposedly last 5 times longer. They haven't broken yet and i've played them for 2 weeks for at least 2 hours a day quite nice.

For all you G-string jokers, i'm sure u've all heard the joke "I broke my G-string while fingering a minor" :P
