The flight packs are more marketed toward those people that have computer radios with 6+ model memory and cost a good bit more than just a flight pack would. It is hard to convince yourself that you should buy just a flight pack when you are buying it for a radio that is only 20 bucks more, but once you have that 4/5/6 hundred (or more) dollar radio, you won't think that the flight pack is such a bad deal anymore.
