The original had a full skirt, I cut it down a bit last night while testing.



I cannot just extend the windscreen, because while it's larger diameter than the heat exchanger, it's actually smaller than the pot itself, so extension wouldn't go over the pot.

I think the original design of the windscreen is only to protect the flame anyway, which it does pretty well. It's not the screen off eta express, it's similar but intended as a stand alone product.
