I have a 2008 Vita sport which is equivalent to the 2009 Vita Elite. I can't compare it to the Trek because I have not ridden one. I really like it. I am 57 years old and also did not want the drop handlebars, but wanted a lighter bike that could keep up.

I looked up the 2010 models that you are looking at and have some suggestions. Do you live in an area with hills? The Comp model has a 12-25 cassette and the smallest chain ring is 30. The Elite and the Sport have smaller chain rings and the cassette goes up to 32. My bike has a 48-38-28 ring and the cassette was 12-25. It was too hard to get up the major hills, so I changed the cassette to 11-28. That works great. It seems like the Comp could use a cassette change before you buy it (if you have big hills). On the other hand, the lower models with the 32 cassette seem like granny gears that you would never use.

I also changed out the 700x28 tires to 700x25 tires. That really increased the speed of the bike.

The reason I am telling you this is that you could potentially get these things changed before you bought the bike and perhaps you would not have to pay as much (or anything) since the components would not be used. I would talk to the LBS about making changes before you bought the bike.
