Very nice bicycle, a good choice for what you say your riding is like. My wife has a similar set up on her bicycle, a 2008 Trek 7300. No disk brakes but she likes the set up, just kind of heavy for what she was used to from her road bicycle days. A seat swap is the only change she did. Post some pics of her and the new wheels when you get the chance.
