I have been riding it that past week and it is a blast. I took it out this weekend for 16 miles of mixed riding. We had street, dirt fire roads, mountain trails and the bike did great. I have a 9 mile commute each way and it is much nicer to throw my stuff in the bags and go as apposed to wearing a backpack.
Are you sure the frame is not too big? Zero set-back stem, seat is moved up and the short stem.
I am not sure how having a zero setback seat post would mean that my frame is too large, I have no setback on my other bikes. I do seem to run more of French Fit on my bikes because I am not 18 years old anymore and prefer a more relaxed geometry.
ThermionicScott is correct, there is a bit of a reach with the bullhorns and it is taking a few rides to get used to it. At first I thought I was going to switch them to drop bars but now that I have about 100 miles on them I actually like them.
Really when it comes down to it I build my own bikes because I want them a certain way, the way that I like them and I love this bike, it kicks ass! Hopefully everyone can say that about their ride because its more fun to ride a bike that you love not ride a bike that everyone else thinks is cool.
