Looking for some guidance...

As I've previously stated, I got my first road bike, not based on testing it out at my LBS, but because it was cheap and I wanted to ride. And it was pre-finding-TE, too.

I just saw the Salsa Casseroll online and it's a beautiful bike! It seems as if it would fit my needs, too - commuting, errands, light touring.

However, I am concerned about its weight compared to my aluminum frame. Is it really going to be that much more difficult to ride up hills? My work commute is very hilly and I don't want a heavy bike weighing me down. I know the more I ride the better I'll be, but I honestly don't want to pedal something heavy up a hill.

I would absolutely try it and a few others before committing to one specific bike this time, just looking for some points of view.
