Just a fast one as I`m on my way out to work,,,,, I`d add more ` curve` around the temple area as shown [excuse my shaky red line--using a laptop touch-pad] ---I`d bring down the ear flaps as shown and come ` down` behind the ears too..... you should consider growing side-burns--makes for a nice natural look which you can then ` blend` the flaps onto.... my experience has been to also ` come down` on the nape area rather than having the perimeter of the system ` high` up on the neck.... I know you`d read that the movement of the neck causes the edge to de-bond there.... it`s not something that`s been an issue for me ... I find that by having the perimeter ` low` and keeping the hair-length there between 1/4 and 1/2 an inch, the hair tends to stay in ` tight` to the neck...longer hair tends to curl outwards and you`re conscious of it all the time, which is what happens if the perimeter is up ` high`...hope that helps.
