The 8.5 is a fine buggy. But for 20 bucks more you can get an 8ight race roller from losiparts. Having owned a Hyper 8 for the last year I can tell you the 8ight is a much faster buggy. Its able to carry much more corner speed than the Hyper. However, the 8ight requires a smooth hand to drive well. It's now where near as forgiving as the Hyper.

Hope that helps some.
