I, too, am a user of used spokes and have been using them for many years. I inspect each spoke carefully to ensure no damage or deficiencies. Then, I put the nipples back on, take sets together with masking tape and Sharpie length on the tape. Then into the box until I need them. Sometimes, though rarely, I even save plated spokes just in case. The concern is, do used spokes stand up to the test of use and time? So far so good, so far prettyy good. For a year or two I ran my Jamaica Bianchi with one broken spoke on the rear wheel. A little back yard mechanic wheel truing and back in business...
