Kona Blast Deluxe Hardtail (http://www.konaworld.com/08_blastdlx.htm )

or

Giant Yukon Fx basic dually (http://www.giant-bicycles.com/en-AU/bikes/mountain/1387/29610/)?

I know it's a component vs frame debate, so I guess my underlying question is, since both are $999, is the Giant decent enough for riding the Manly Dam, Ox Falls etc, or will the lighter weight and better componentry of the Kona serve me better in the long run?

These seem to be the go at their respective price points, but any other suggetions for a sub-$1k bike for trails wul be welomed as well. Cheers!
