Uhm... the opposition is made of.... uhm... METAL!?!?? How COULD it be "up to par"? lol
The whites that have failed (not EVER... just within an unsuspected range of.. lets say 100,000 miles) could probably be counted on your hands and feet, VS the black ones which are currently sitting at an estimated
658,245,858,900.89 failures.
Metal ones have failed too.. They don't shatter (obviously) but failure of leakage through the shaft itself is been ABOUT as common as white impellar failure.
My stance is:
white, metal, whatever.. just anything but the original.
