The other snag with hook arrestor systems is the required moification to the airframe to prevent it being ripped in two by the decelleration.
The system has to be tuneable to the landing weight of the aircraft to provide the 'correct' resistance. Have a look at a few old vids from carrier deck landings where the arrestor gear was set for the wrong aircraft!
There is no point in preventing runway overrun damage when you pull the tail off!
