There are two things to keep in mind when using tape on the spine of a wedge while honing. The tape must be centered on the spine so equal amounts of tape extend down both sides of the blade. If the tape extends too far down the side of the blade you wind up resting on the hone with the bottom edge of the tape and not the spine so you may have to use a narrower piece of tape. That is because of the very little to no concavity of the blade. I think the linked article explains and illustrates that very well. I think that is what makes honing wedges a little trickier than hollows. Other than that, they hone like any other straight from what I can see.
