no there is more in there than the turf to hold the door on it. turf could tear, and then you lose the door and extinguisher. I would not do that. it has multiple straps as attaching points.
Don't you use web strapping applied into the wet glass?
I've seen the Tom21 hold. It definately has more holding it together than the turf. I like the way he did the hinge. I prefer to have as little metal on a ski as possible.
That Fx1 clip is just super clean. Great idea.
I do really like the look of the Pete hold.
I've ridden a few skis with front foot holds, but I never asked, so the only hold I know I have used for sure is the Tom21. It fit well but I don't have anything to compare it to.
