I'm kinda late to the party but I agree with RotcanX above and I'd further mention that with the bolt-on, the neck overlaps onto the body so the overall length of the guitar is shorter which means the bridge needs to be positioned farther back on the body which changes the entire geometry and balance of the instrument. If it's any consolation, one advantage of the bolt-on SG is less "nose diving" of the headstock :)
