I have done a lot of work with and prefer AFF Foam systems.
A 9 litre tank in the boot with 5 micro nozzles is a good compromise between protection v's size/ weight.
Most of the installs I have done have been 2 x 106 ltre, 4 x 106 litre, 60 litre and a few 23 litre. They are good for industrial equipment but I wouldnt like to be dragging that sort excess weight around in the cobra.
You can set up a Loss of Pressure system (LOP) which may go off if you ever get a air leak in the holding system, or a Rise of Pressure system which burns a wick that makes gas pressure to open the valve and release the goods.
LOP is probably the better system in event of a fire but ROp is less prone to false triggering.
