When I do my lunchbox delete this weekend, I will probably install an angle to the valance to try and keep the flap to a minimum. Or so I hope. I would imagine that if I face the angle forward that it should not only stiffen up the plastic but also help deflect a tiny bit of air downward.
Idk, we'll see what happens with it.
