Picking a higher density of the material just means the one gram would occupy less volume, it doesn't affect how much energy that gram is equivalent to in terms of E=mc2. For that calculation, as the equation implies, only the mass matters; a gram of feathers is equivalent to the same amount of energy as a gram of lead for that equation. Now, this equation is in fact a simplified assumption; if you launch your feather at relativistic speed, then we're talking

This is true. This is why I compared them using the fixed volume of one cubic centimeter rather than using something like specific gravity. The only thing that differs is the mass, which is of course, directly proportional to the energy.
