PA 12 roof loading tips

Can you tie down through the peddle drive? I have the 360, so worried that theres gremlins I might smush:) The front of my kayak Keeps going all over the place and trying to take flight. I tie down using the dreaded Rachet ties bc the buckle style doesn't work either, and keeps getting loose. I tie the back down through each supper hole separately, using 2 tie downs just for the back. I have two long buckle type straps that I wanna use, but don't trust. Any help would be appreciated. I load on a tall MDX, Ive read that your supposed to load upside down, but with the rudder and 360 controls, that's outa the question. Tips?
