Very interesting thread - I’ve just taken delivery of AFS silks, and in terms of surfing they’re insanely good - just moved over from lift.
I’m still figuring out the silks. The pump initially felt slower and less glidey than the ha120 (which I am still in love with), but what I have noticed is that subtle changes in technique keeps unlocking more pump and glide on the silks. I feel like once I unlock the changes needed, the AFS will be just as good. They’re incredible wings.
