Note, I did not say running chmod on the link, I said chaning the permissions of the link and was speaking hypotetically. Running chmod on the link would as you said change the file, but there would still be no effect on the link itself: it would still be 777. The point being that changing the link is a pointless exercise, the actual target should be modified directly if this is required for some reason, but I cannot see a reason for changing any of the ones suggested.
