Someone asked me about the special challenges of a full cap. Overall, I am much happier wearing a full cap compared to a topper with thin sides caked in concealers. But here are my biggest challenges.

-the nape doesn't stay down for me that well attached with even the strongest glue I know of, ultrahold. With strong tape I imagine it would hold fine. But the tape would show through at the nape in my current full cap. The nape has the shortest hairs and is the least dense part of my piece. You have to realize that there is some tension on the piece in the nape area below the bone because of head tilting.

-the temples have a tendency to ripple a tiny bit, at least for me with Swiss lace. I have to be painstaking in my attachment. Practice may or may not eventually make perfect.

There are other relatively minor issues like a little more money for the full cap and more adhesive needed for attachment. I know Jrob wrote a post on this too, but i cannot find it here right now.
