BFS drops composite construction

I saw a report today that SpaceX was dropping composites for tanks and main structure on BFS in favor of using "heavy metal" (Musk's phrase). It's unclear why the change, although it's probably a cost/schedule move. It's also unclear if this change is permanent or if it's only for early ships. Also unclear what impact this will have on payload, since BFR will now be lifting a much heavier BFS than was originally planned. All these changes are both bad and good. They're bad because of impacts to weight and such. They're probably good in that they indicate that we're close to actual development and that is driving changes. Scott Manley has a video about this. https://www.youtube.com/watch?v=VoegqRJKGE8 It may not be a reaction to technical difficulties with composite, but a design decision based on the specifics of the BFS.
