Nice ride! I hope you enjoy it!

I do have two small criticisms, though, and I don't mean any disrespect here, but:

1. I think your rear rack installation could have been a little better. If you can't get your old rack to be parallel to the ground, then you should consider getting a different one.

2. You may want to reconsider messing with the headset very much. One of the reasons the bike is pretty comfortable is that you're a little more upright than you'd be on a road bike. As long as your back is at a 45 degree angle when you're on the hoods, you're probably okay. If you need to be more aerodynamic, that's what the drops are for.
