I use tape occasionally, but I try to avoid it. Taping DOES change the angle of the bevels on the edge, so you'll need to reapply the tape if you go to touch the razor up on a hone.

You don't need to leave the tape in place for stropping, either on a paddle strop or hanging strop. There's enough give to the leather to compensate for the slight change in angles.

If I really need to tape the spine on a razor, I will often do most of the 1K work with the tape in place, then remove the tape and do some more laps to fix the bevel. Kind of the best of both worlds.
