I have both a Diamondback Expert TG (same frame as yours, OS Tange Crmo) and a Tange 5 Ricardo. Although the Ricardo uses PG tubing, they are standard sized and I would choose it over the Diamondback any ride. The DB is just to stiff for me on the roads I ride. I prefer a frame with a more flexible top tube. I think a thinner standard size top tube with a decent set of compliant forks, instead of the ghastly uni crown ones it's adorned with, would make the DB a much better ride.
I think my take on smoothness is more the rolling feel of the hubs and the bottom bracket. I haven't ridden enough to start comparing how frames contribute. I'm sure that when I fit up the new GPX stuff the smoothness will be awesome!
