I also rode the Cannondale Caad 9, and although new to Road biking, I think you guys owe yourself a test ride. I thought the frame was a lot stiffer than the Treks', and just as compliant as the 1600. I also think the frame was better engineered when you look at the shaping of the tubing. I can't wait to ride an Allez to compare it to the Caad9, but if you guys are saying its a toss up between the two, the Caad9 is gonna be my next bike!
