I am going to purchase an AT80ED for grab and go. For a mount I am looking at either the Twilight 1 or Porta 2. For grab and go the Twilight 1 tripod doesn't fold up easily with the spreader in place. I don't know if it can fit through a doorway without unscrewing the spreader and folding the legs. This issue brings me to the Vixen Porta 2 head and standard aluminum tripod. I found one video online which shows the Vixen spreader folds up with the legs for much easier grab and go out the door. Can anyone who owns the Vixen tripod confirm this?
