Maybe I'm just the suspicious type, but...
If you've got one spoke that's a bit too long and poked through the rim tape of unknown provenance, how do you know you don't have multiple spokes that are too long and getting ready to poke through the rim tape? I'd rather put a roll of new Velox tape on and then I could ride secure in the knowledge that I had good tape on and I wasn't going to have any more flats from that source.
