I, I'd imagine like a lot of other people, sucked with the sheriff. I saw a post a while ago saying that getting really good with the sheriff improves your aim a ton. I decided instead of light buy being a spectre, buy a sheriff and light armor. Instantly, my crosshair placement was 10x better. I was able to avoid spraying and tap fire way more than before. My aim improved way more than it did using aim labs or kovaaks.
