After 4 years and over 200 passes with my GRP rods they look NEW, had them check and there was nothing wrong with them, I did replace them last year. I've ran steel rods (Oliver, Eagles & SD factory rods) and every time I inspected my rod bearing they fell out, with my aluminum rod my bearing always look great and fit tight. I would never run steel again of course I do run a Blower.
Kelvin, after 350 plus passes I think they (rods) held up great and you without a doubt got your moneys worth out of them! Good Luck!
