I gave my sail a once over tonight before putting it away for the winter and found this. The bottom cam from a Overdrive M1 was a different shape on one side. I have to think it's been worn down but can't for the life of me think how it's worn where it has and why only one side and on one cam?.




The top pic is one side of the bottom and second cam the bottom pic is the same cams but from the pther side where you can see the difference in shape
