According to Dave Tutleman, bearing type finders can be confused by finding the residual bend, and not the true spine. There is no point in buying shafts that have been spined but not tipped, as I've seen the spine move after tipping. Now, this could be the residual bend that's shifting, and not the actual spine, but I haven't checked this in my NF4.
