I have a sneaking suspicion that the FWs won't need the spool springs as much anymore too... money saver!
BTW, if anyone's interested in the articles I found to tell me when the wood spools were discontinued, they're below. One article written fairly recently, and 2 newspaper articles. The newspaper articles are fun too, because of the other articles, and the "funnies".
