Road Morph for both of my road bikes. Now even some of the guys in my club have them (after teasing me for getting one!).
Mine is mounted on the down tube next to my water bottle on one of my bikes- on the left side. The other is mounted on the seat tube also by my water bottle (on the left side). Depends on size of your frame. My carbon bike has a big top tube so I couldn't put anything there. Just put it somewhere so you won't notice it when you are cycling!
