Seems like you are asking too much. For me, a commuting bike and touring bike are way different. Light and burley? My good weather commuter is a cross check, full steerer tube, short, steep stem. My current touring bike is a Karate Monkey, flat bars with a sweep, plus bar ends. For me, that ends up being upright with multiple, comfortable hand positions. Not light though with a sus fork, 35 mm rims and 29x2.3 slicks. But burley, great for dirt roads and single track. First decide if you want flat or drop bars. So many options in the drop bar adventure type bike. How wide of a tire do you want to run? Fenders, racks, frame bags, bottle mounts? All things to consider. Spec, Kona, Salsa Jamis and more to look at.
