Upslope/downslope RWY
Never been there but it sounds like some of the places I go in and out of. I also do line checks on thease routes and a little trick I use when I want to see if they can stay on the profile is to have the tower turn off the vasi and you whould no beleave how many will go low on the down slope and high on the up slope. Just my 2ct's worth.
Safe flying.
