need some feedback between Diamondback overdrive pro and a cannondale

[slimdaddy1973]

I owned a cannondale F4 and rode for a local bike shop in several competitions. Have not rode since 2003 after a injury. Now I still feel the need to clip in and hit the trails. I'm looking in buying a new bike but I've been out the loop for sometime now and I need some insight. I really like the the Diamondback Overdrive pro but I was a hardcore Cannondale rider. Any pro's and con's on the DB? Any suggestions on a Cannondale? I'm strictly a hardtail fan. Last but not least, do anyone know any good trails in the Piedmont area of VA?
