I've noticed, now that I've goot a good backpack, that the design in the back piece pushes the backpack out away form my back by a quite a bit. I'm thinking of modifing a mold to not have that part and only have a flat back piece in order for the back pack to sit flush with my back.
Looking at the movie caps I can't tell if it would be cannon one way or the other. there is no direct side shots but all the slightly angled side shots make it look like thier backpacks are flush.
What's eveyone else think? and would anyone be interested in them if I pulled them?
