Back in 1980, I tried my cow-orker's Serotta. It was a criterium bike. It was so nimble, I was scared out of my mind. Plus, I was used to riding 58cm bikes, and his was about 53cm, making it even more nimble.
You really should get moving with building your Miyata frame. It will might give you a ride comparable to that of a good Serotta.
