I think NW5's have a very hard time with pieces. Not only do they have to shave an oval patch to the same size and shape as an oval piece, but their piece has to mimic the spiral, and they have to glue in on right in back using a mirror. Many people's hair parts right at the side border of the piece. They need skill to pull that off.
Imagine that I'm sticking my face into a pool of water, with my face pointed straight down, and my temples submerged 1 inch. All the hairs underwater are getting shaved. The back of my piece is flat and straight from top view. All i have to do is back it on, and I can see it easily from the front. My side hairs go back, and my top hairs go forwards, naturally, which will go over my near perfect transition. I'm sending in hair samples to match color and wave. I'm getting 65% density, and changing my temples and hairline only 1/8 inch. My hair will be real hair. I think I'll be fine.
I just need to get good at applying a very thin, even layer of glue, and need to memorize some reference points, and give it tension and pressure without pushing the piece hair into the glue.
