Coat Sew Along - Interfacing

So here's an article from Threads about Armani jackets. They fuse-interface the entire jacket. Is that really what I should be doing???? I have access to nice horse hari canvas here in town so I can buy it whenever. Should the whole thing be interfaced with it? It looks like this shows "body weight" and lighter and heavier than "body weight". What is body weight?? My jacket isn't exactly like this. There isn't a roll line for the body of thecoat, just the collar. The directions for the coat say to interface the entire thing. Hmmmmmmm. I don't want to do the sew-in interfacing. If I did, I see the post on the Coat Sew Along site about where to interface it.

More pondering.
