Hearing about situations on others loosing their foiling gear or the Hardware loosening out on the water, how tight is safe for fastening those screws and bolts to the board and slingshot foil gear? Should it be as tight as let's say, you fin is on slapper boards? I feel like I'm cheating on the foil hardware, because it's an Allen wrench instead of a Philips screw. I can get more tightening power from the Allen wrench. I don't want to over or under tighten.

Thanks!
