Looking for some help.
I'm in the market for a new bike in the "around" $500 range. It will be used 70% of the time to get me to and from work, and 30% of the time riding midwest trails with friends. I've been looking at several bikes and have narrowed it down to three.

'05 Specialized Hardrock Pro disc. - $570
'04 Marin Wildcat Trail - $560
'05 Ironhorse Warrior Comp - $500

I've test rode all the bikes, and the Ironhorse is a distant 3rd as a result. The Hardrock, and the Wildcat both "fit" real well. Any advice between these two bikes?
