The Norco looks pretty good. It's got nice components and you can lock out the fork when you're riding on roads. But cachehiker is right, ride every bike you're even thinking about and get the one that you like the most. If the trails you're talking about are wide dirt paths through the woods, the Trek 7.5 will be fine. If you're thinking about taking it down the side of Mt. Whistler (and you really should be!) then even the Storm might not be sufficient (although it would definitely work on the less technical trails at Whistler).
