The idea with foot hooks looks excellent
Although, having ridden more now, I must say I prefer either strapless, or fully strapped, no doubt at all.
Strapless goes for itself why, especially the freedom of the front foot.
Strapped you want full straps for racing, as you can put more pressure on "everything" this way, and even rescue mistakes much better.
If jumping they are also needed of course, but for those riding both hydrofoils AND other boards a lot, jumping does not seem to be the big issue (at least not what you see around).
Those almost only hydrofoiling, they jump more than others - maybe because they are more skilled, but maybe because that is their only chance to do jumps.
For new riders though, a foot hook (front one) or hooks, looks really awesome
As you WILL chrash a lot, and might get you feet twisted, particulary when learning
Also, you WILL need a strap or hook, to be able to start safe and easy, and also to be able to start fast again if only fallen backwards (not possible at all strapless)
Yes, many uses one foot strap only
But to me that is a big no no and I would never do that, except maybe for low wind or when going slow
Just like you would never ride waves seriosly on a waveboard with only one strap - it is both or no straps
Here a front hook would be excellent though, for choppy conditions on the wavefaces and when going out fast in chop, where it makes good sense with a front hook on a waveboard
Dont know if I am right, but thinking that hooks are awesome for new hydrofoilers as said, as less risk of an injury, and much easier to learn to foil.
Later I think you want either straps, OR strapless, is my prediction
