Keeping the lace front, right?

This would be a very durable piece that would be great for frequent removal using tape on the sides and back. The poly holds the piece in shape well (easier attachment) and there's no worries about pulling hair out when you remove the tape.

The biggest downside would be that you might spot a poly edge at lower densities. Minor downsides would be that it's extra material on your head, and it's possible that a loose poly edge would be more detectable to touch than all lace- but if you tape it down with tape just a bit beyond the edge it should be ok.
