Has anyone actually flown the entire arrival on the 36s all the way down to 3000' (or whatever the final altitude is)? It seems to me after flying the LTOWN6, MONNA, and one from the west (can't remember the name.. typing from memory), that they take you off after leaving 10K and level you at about 6k. Also, how come when you select a north arrival it includes points on the south arrival with no notation that it doesn't apply to the north arrival? Should be obvious right? We all know how common -- common sense is!
ODP makes sense in LA. Most arrivals are from the east and you land to the west. The ODP puts you right on final. They often clear you the approach during the middle of the arrival. I don't think I've ever been given an exception to the arrival. Ever fly the redeye on a Mem AM departure? They send you out over the water and clear you the visual back to the east. LA uses an ODP when it makes sense.. landing west during the day.
Instead of using an ODP, why not just have everyone fly the same airspeed on the MEM arrivals? 3 degree descent, level at 10 or 12k depending on north or south, and common airspeed? Pick-off cross-runway as required.
I'm just a lowly peon, but maybe the confusion with the ODPs at MEM so far is because an exception to the arrival is really the rule....
