+1. Good old butted steel frame but the Zaffiro tires won't do packed gravel trails very well. Check the tire clearance and find some suitable 32-35c tires for the trails. My Aurora wouldn't handle 35c casings without swapping in some Thinline brake pads. As a later upgrade, consider putting the original tires on some better wheels to swap in for dedicated road use.

If you want clearance for bigger knobbier tires that will handle the trails better, look at the Treks. They won't be as comfy on skinny tires but will likely handle 38c or 40c tires without fenders. And forget about the suspension fork if you're going to ride 90% road and shorter trail sections. They're OK if your spending less time on the road and riding longer rail trails and the like.

I've heard the Sirrus has a more road-ish geometry which could be problematic if you hit the trails and lack solid bike handling skills.
