The 812's are the same as the 412's, except they are in a prettier package (i.e. flames, slash cut...)
I might have probably gone with the 418's in heavy duty if they came covered or even with chrome caps, but I don't like the look of all that spring.
The 440's are supposed to be the best, but they don't come in heavy duty or I would have a set on my bike.
I ended up with the 412HD
