That's funny because I thought the same thing. I love the #87s. But everyone has them. I was looking for something a little different, I saw the #168s, and really liked them and thought I had decided on getting them when I get my X sometime this coming summer. But then I saw someone with #132s in 20" and I know not too many people have those in 20". So I asked the question to see what everyone here thought. I still like the #168s. I'm so undecided.
