Agree.Ii don't think a rear strap is needed on the 80kg+ boads as there is a lot of windage with them. As the boards get smaller though, jumping is more likely. And not impressed with the video on the HIPE page showing a jump at around 10? seconds- freeze is and you'll see it's with a non HIPE board that DOES have a footstrap. Misleading.
Pity because with the USA box mast mount, should be easy to ballance load point relative to straps.
But I'm so new Still to get up and foil!
