A locker will get you further than MC fenders will any day of the week. I have MC fenders but also have lockers, but in your position I would rather have traction. I would rather make the climb that some cool guy with his MC fenders at the bottom.
YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE DUCT TAPE.
IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.
