I have a MTB set up for trails, an older MTB set up for multi use paths, and a hybrid that I use for exercise and local trips. I just purchased an older, mid-quality road bike. This last bike is the closest I've ever had to a real road bike, and I really like it. Unfortunately, my neck doesn't, so I'll have to modify it. As has been said before, why limit yourself to one style of bike, especially if you're willing to work with used equipment that cuts expenses.
