Been looking at these (and the Expedition Saddle Bags) a little more closely, and got to wondering - Is the seat strap really neccessary? Is it a weight-distribution thing (especially considering that the Wolfman Pelican box / hard pannier mounting kit seems to simply holds to the rack)? Will they hold securely to the rack without the seat strap in place?
