I like what i see....the only concern to me would be the dip of the fwd edge of the track for the Edge being that the Flex is flat. I guess a lil' roll of the track on the front would solve that problem ? The forward crossbar of any system must be mounted pretty much where the roof starts to dip to be able to install any kind of lengthy 15 to 16 cu. ft. cargo carrier without the box hitting the rear hatch when opened . Ford"s factory rail system is "junk".....the roof rails are plastic and when factory crossbars installed , only accomodate "select carriers" according to Ford. The only carrier that system is good for is basically a "bag" to be safe !! or smallish hard ided carrier. Gears are rollin on permanent track system....pretty much the only way i see put on this point. thx for info rwolson.....will update with terminating fix !!
