I've repaired over 10,000 ambassador reels and other than an issue they had with the 6.3 gears when they came out with the C4 series I can count the number of main gears I've had go bad on my two hands. In truth the gears just don't take much abuse as that's what the drag is for and even when "locked down" it should still give before anything else breaks and for the gears to go the anti reverse would have to break first. And if the anti reverse breaks you have a mess on your hands!
