Also a question for someone with experience in this area: In the US, Halon is readily available. It's not manufactured anymore, but there are large stocks available and legally offered for sale, so most common options here are:

Halon (two types: 1211 and 1301)
FE36 (halon replacement, although seemingly not as efficient)
AFFF (aqueous foam)

and some others, but broadly falls along the lines of Halon, halon replacement, or foam

If I decide to plumb in a system, go for Halon then? any ideas about optimal size - as big as can fit or...? (Halon is sold by weight - 3lbs, 5lbs and 10lbs are common, whereas foam is sold by volume 2.25L or 4L)

The Halon replacements we have in the UK are supposed to be as good as Halon. I have a Zero 360 lifeline system with 2.25kg of gas (4 nozzles for the engine and 2 inside the car) This is the MSA aproved size for race/rally with that gas. FEV also do an equivalent same sized system. Personally I would go with a gas sstem as it is more effective than Afff and if it goes off by accident it dosent make a big mess! On the down side it is more expensive.
