Generally a 2-4" pin distance is a good range. try to stay away from the extremes (0-1" pin or 5"+) unless you have a particular layout in mind. If you want something with the pin above your fingers (little more length), then side towards the 4" distance... if you want a little earlier rolling ball (pin under fingers), side towards the 2" range. As far as top weight, 2-3oz is a good range.. basically its going to tell you if (and how large) a weight hole is necessary for a given layout.
