For absolute max performance, I would say the GL back wings, as these are smaller/flatter/thinner, but it depends on the size obviously - the 1305 for example has massive lift and does really need the 220 to balance. The smaller Glides with their smaller back wings should work great for windfoiling, especially the 725/905 - I know from own experience when our Product Manager Daniel Aeberli was whipping myself and our foil designer with those on his windfoil vs us on wings, using same style, in some racing in January in South Africa.
