Ahaha, nice Air. I myself am crazy, at least in non R/S I know I am, when it comes to speed. Although I'm not always the most efficient going across maps, when I bear down on someone I zig-zag towards them and go nuts, I learned this like said above, from an auto(HK MP5 1.2.1), and now that it has been nerfed, I have adapted this rushing skill with the Desert Eagles.
I agree with the statement said above, however fully fledged Barreters know how to play passive, use their nades, and back up weapon efficiently.
at one point I almost had as many nade kills as rugar kills in my rs stats
