Bob,
Except now your friend has to put his original address back when he returns to his home layout.
Personally I like the Zephyr with the direction/brake lever for mainline running, and the Atlas Commander for working in yards and large industrial areas. The direction buttons on the commander make is simple to do the "Kadee Shuffle" over the magnet when uncoupling knuckle couplers.
