I swear by Rizoma. I haven't got their bars yet, but I plan on it. From what I hear its mostly a cosmetic upgrade, but with new risers you can make the bars higher or lower depending on preference. Hope this helps
I just put the Rizoma's on, and I have to say that there is a difference. They sit higher and are swept back more. Definately will take time to get used to, but my wrist are much happier. As for control, having the bars higher will make it turn slower. You will need to re-learn your lean.
