It's hard to tell what will happen with a change request, it depends on if your order is matched to a production batch. If you are far enough back in the line, you can make whatever changes you want and it will not make a difference. If you are slotted to a production batch and you make a change that moves you to a different production batch (for example change color), then you run the risk of getting your order delayed until the next production batch with an open slot, which might be a little time or a lot.Good thing 3 separate told me changing colors didn't matter and wouldn't push me back.
