Don't overlook an important fact of bridge glueing: If your bridge Does Not come off in times of great stress (the car trunk in July) your guitar's top will end up resembling a wavy potato chip. The glue used to fasten a bridge needs to have this "release under stress" ability. $10 garage sale specials being the possible exception. Also check out a few bolt-on bridges that have wavy, distorted tops because the bridge couldn't fly off.
