colas said..Don't forget that the foil also plays a role for lowering the necessary wing speed, and also now the board with the new DW shapes.
So you do not need to go to huge sails that can prove heavy or cumbersome in flight but also using a low wind foil & board.
People that are exploring the low ends are using a combo of dedicated wing/foil/board
Example with a 100+kg guy :-)

I'm separately optimizing for these factors in the setup. Just trying to isolate the wing as a variable for the purposes of this conversation.
For the stated purpose I will be riding a mini downwind board (5'7" long, 20 wide) and an efficient foil setup. Given the difficulty in comparing setups I was hesitant to put a wind range on anything. I'm not necessarily looking for a lightwind wing (I have those) I'm looking for a maximum efficiency / nicely flagging wing (although these characteristics are likely overlapping). For example, I can get good downwind conditions in 15-20 knots (which I wouldn't consider to be super light), and want to use the smallest wing possible.
Thanks for all of the options so far. There are some very promising ideas here. Probably going to see how low I can go with my existing 3.5 before determining whether to get a 3 or a 2.5.
