I didn't see a mention of it, but as much time as you're spending researching bikes online...spend a corresponding amount of time finding someone in your area that will fit the bike properly and follow up once your body adapts to road cycling. Fitting is one thing that a lot of people tend to overlook, but you really *need* to do it to get the most out of a bike. The difference with my F5 was night and day, and it wasn't uncomfortable to start!
