Like I said before the nape is an issue. It's all about the placement on the nape!

You cant go too high, because it will become loose.

And you can not have a buzz or fade at the nape. Because you NEED to attach onto the neck. It would look weird having a buzz, without the back being tappered lol. For longer styles though, the fullcap owns, because the hair flows more randomly and naturally and you don't have to worry about the line.
