Special effect or Dummy (missile - efficiency)

[Rasamayu]

Hi hive, I have a question about which is more efficient in this case:
I want a normal unit to work like a missile, so I make it transparent to visually put the "new unit model" on top of it (as if it changes models, when it really doesn't). This can be done in 2 ways, by creating a special effect that will constantly follow the unit OR by creating a new dummy unit with the new model that will also constantly follow the original unit.
Which of the two ways is more efficient, consumes less RAM and generates fewer leaks?
I am comfortable with both ways, but I want to know which one is better in terms of efficiency.

Thx

What about the third option: Use only Special Effects

The Wonderful World of Special effect Modifications!

My Intention with this tutorial is to inform users of the many useful ways they can modify special effects to their advantage, we will be exploring what, why, and whatever these modifications may pose to our merit. Something of note: @ThisPOT made a rough draft of a projectile system that uses...

Though this depends on which version of Warcraft 3 you're using.

Anyway, it's safe to assume that a Special Effect is less taxing than a Unit. Think about all of the properties of a Unit vs a Special Effect.
