I've had the Loomis Max Linespeed for over a year with no problem and three other 'old school' GLX's for several years with no problem. The GLX's were my everyday, go-to rods and saw a lot of use.
I do treat my rods like they are made of thin tubes that can easily be broken though... especially if you add stress-risers like chips and nicks.
A lot of the time I think broken rods boil down to operator error. Within a week after selling one of my GLX's the new owner broke it!
