As for the OP, there's a laundry list of reasons i'd go with the 7.3 over the 7.2, you're getting a lot of upgrades for not a huge price increase.
I disagree. I have a Sirrus, Comp, with a carbon fork, and the carbon rides much smoother than aluminum forks. It really is noticable. Road buzz is almost non existent. As is handling of ordinary bumps.
Granted, its not as smooth as my suspended crosstrail, but it really is a much nicer ride.
After having this Sirrus, I would definately opt for a carbon fork.
