I am using the 1350 for both wind and wing foiling. The glide-ability and high speed are an improvement over the 1100. BUT, the width is a deterent for hard carving. For super light winds I considered the 1550, but saw comments that it's hard to turn, so I got the 1350
For the 1100, light winds and waves (carving)...900mm FUSE

For the 1350, light winds and flat water (pumping), winging, eFoiling I use a shorter fuse.
Stringfellow/Moses Custom Fuse 710mm,
