I only use a coiled leg leash attached to the bar below the bung hole, and run it through the space between the foot plate and the side of the ski. So it goes "down" just like yours, I think.
I do not have it like that in the picture, but now I keep most of the coil on the venturi side of the foot plate and just enough on my side to not have it dancing around when i get on and off. When falling, only the necessary amount of leash gets pulled over to my side.
This is a 10 feet leash but the coil is still tight. My previous one was more tangleprone the looser the coil got until a beachbreak wave converted it to a completely non coiled leash. After that I never got tangled, seems counter intuitive because the coil is supposed to keep it all nice and ordered, but the noncoiled ones just lay flat.
