I like #2, #4, #6, & #7.
8 & 9 are a little too busy.(Especially #8. I can't hardly read it)
I haven't voted yet. I really like #6, but I think if it is the chosen one "TSF" should be added in front of "Folding@Home".
I have hit my signature limit, and will likely not use the chosen banner, but I commend all who have submitted banners, for your hard work.
Jack Sparrow should have submitted his also, nice banner Jack.
