How about doing some research yourself. Look through all the examples and then tell us which one you think it might be. You will maybe start educating yourself at the same time.
Similarities don't work with DDO's or DDR's. They either are or aren't. Your is definitely not FS-101. The doubling doesn't even come close to matching. Not to mention the mm placement doesn't match.
