George,
I still don't see anything that requires both ends of a metallic service raceway to be bonded. On the line side of the service disconnect the grounded conductor is used to bond the service equipment, the equipment is not bonded by the service raceways. I always thought that bonding both ends was a code requirement because that is what our local utility requires, but I debated this with Phil Simmons (CMP5 chairman) and lost. The code only requires one end of a metallic service raceway to be bonded. If you want to bond both ends, that is fine, but the NEC does not require it.
