An AB rating means that the FDA has determined that a generic medication is equivalent to a brand-name medication. All of the generic clopidogrel versions currently available have an AB rating, meaning they should be equivalent to Plavix.
Warn stouts its M8274 as the winch with the fastest line speed. The Warn 9.5 CTI is a nice winch. Unless you winch every day I doubt you will notice a couple of seconds on your wind up speed. =-) http://www.clemson4wheel.com/warn-38...ies-winch.html.
Kingda Ka is the fastest roller coaster in the United States. It was the fastest coaster in the world for a few years but has since been eclipsed. (It is still the tallest, however.) It's similar to Top Thrill Dragster (although faster), but it feels rougher. If speed is what you are after, Kingda Ka delivers.
