I just picked up an 08 Scott Spark 20 and am overwhelmed with it. I also saw the Scott bikes at Interbike in Las Vegas a few weeks ago. I have never ridden a Felt, but I know they have a solid reputation. for me right now I am drinking the Scott Kool Aid!

The bottom line has to be fit and feel. I switched from a 20" to a 21" frame. Its a more comfortable feel for cruising and I am getting used to it in tight situations. Good Luck!
