To some extent, even more so than lapping, the discussion of whether or not to tape your spines is largely philosophical. Pursing this as a hobby allows us to get lost in minutia. Take lapping for example. Did guys who shave with a straight their entire lives obsess with lapping their hones? How about barbers, whose hones saw far more use? Chances are pretty good that they used them until they didn't work well then lapped them. The point is that no matter which way you choose, with tape or without, you can produce edges that shave very, very well.
