Hi all, i have been bitten hard by the MTBing bug and would like some advice on picking my first bike.
I want to start using the many trails in the south wales area and i think a hardtail would be the best starting point for me. I've got a few in mind but my spec knowledge is non existent so any input would be welcomed. My budget is £600.

After searching the web the 3 that standout to me are...

Cannondale Trail SL 6 2010

Kona Blast 2010

Specialized Hardrock 2010

A friend of mine has a Marin bolinas i've had a go on it and really liked it but i'm not sure its for me.

I hope this all makes sense and any advice or recommendations will be appreciated.
Thanks, Lewis.
