Thanks guys. So will french lace give a good invisible look for the front hairline? When I ride the motorcycle I plan on always wearing a bandanna just to cover the front hairline to keep dust and dirt out of the glue.

As for the sides and back where the piece will mate to my natural hair, I was looking to see where they would meet and the hair is about an inch long there and tapers quickly down from there. Do you think that's long enough to make a good invisible joint? Considering my hair is fine and probably 50%-55% density.
