ok, just ran this through a couple of times and my favourite was 'c', i also think this was the m148 source, real smooth and a great low end. from what i've heard about the m248 i'd have to say that was 'b' as it was the brightest of the bunch and that leaves the 722 as 'a'. that being said, i could be completely wrong.
brett.
