Do it, it's the best new experience for me since starting waveriding.
This is bringing the fun of riding waves to chop and small waves.
I use a Slingshot Infinity 84, short fuse, small rearwing, 70cm mast, position B setup, mounted at the very rear of my us-rails for supfoiling. This is about 42 cm back of mast to tail, inbetween the supfoil postion at 50cm and the position of my tuttle for my freerace windfoil at about 20 cm back of mast to tail.
The ride is strapless and in a more centered position, sooooooo fun.
But switch off your learned cuback technique with a hard turn over the backfoot. With a foil you get some serious aerials with this.
Freerace foiling for me only happens on flat water anymore.
