The infusion already has 16:1, why add more?

I find the downhaul struggles to ease with 16 to 1 all you need to do is add a line under the sail attached to the mast on either side and to your normal downhaul to double your current purchase but its tricky with space. would it ease with any more purchase?

The race package stock is 16:1 through a cascade (blocks on the clew + clam cleats on the mast by where the diamond wires enter)... without the cascade you only have 8:1.
16:1 is definitely enough, we've ripped our main with it! And it was less than a season old.
Check out the Nacra Assembly Guide online, P.18 i'm sure you can find a picture of it.
And the downhaul runs a lot better with a small line (4mm). We are running 4mm FSE Robline Dinghy control and it runs very well and uncleats from the wire everytime no matter how much pressure.
