What I've always been told is that you should use smartwebmove first, always, unless you need your pick-up/move to begin in 7 days or less. In that case, go right to the PPO and have them manually put you in the system for an earlier date (than 7 days out). But if you can wait 7 days, smartwebmove will do it all for you and get you the earliest date available at the time of submission.
