Your 700c conversion looks really nice, good job!
The one thing I didn't like about my Strada was the distance to the ground. I felt like I was doing the splits at stop lights; one foot on the pedal and one foot on the ground. How much did 700c wheels raise your seat? I'd guess only about half an inch, or so, but still....
I agree that 700s roll better and there is a better selection of tires.
I have a conversion, as well. It used to be an el cheapo mountain bike. Now, it's a Cruzbike and has quality components on it.
