Assembling with a box is the fastest easiest way.
Tuttle is overkill IMO, only for racing it gives extra support and they can use thicker boards as they are very deep.
KF Box has the advantage it is smaller, and conical sides, so it wont get stuck like some Tuttle box'es can.
KF Box can be used with 1 or 2 screws, and they are aligned with the mast meaning square to the board surface, opposite to Tuttle that is made for windsurfing at the back, thus tapered and does not fit foilboards well.
This can be overcome by using a special Tuttle box, and have the head with screws aligned with the mast, so possible.
KETOS use KF Box with 1 screw, thus the fastest and easiest to assemble, I love that and important for me it is as fast as possible.
No wear at all doing this, nor with a Tuttle.
