The solution may not be a tool, but simply not following so many people (particularly "noisy" ones). I've also turned retweets off for probably two thirds of the people I follow, so that also helps. With few exceptions (for especially interesting/notable accounts e.g. NASA, WSJ, HN100, etc) I try not to follow people who tweet more than two or three times a day (shameless plug: I created shouldifollow.com so I can easily see how often someone tweets before following them).
