Difference between 2007 SST and 2008?

What are the differences between the 2007 SST and the 2008? Is it just graphics? I know Liquid Force is coming out with an Aaron Reed graphic. I have seen two different SST 42s. I currently have an SST with red letters and nautical stripes on the base, but there is no continuation of the bottom graphic on top, it's just black. I know there is an SST with yellow SST letters on the base but i'm not too sure if there are other differences. Can anyone help me out? Besides graphic, is there a difference?
