Hi Emmet,
That hair is very thick---I thinks it's 75-80%. And you're right about it being easy. With no hairline exposed and that amount of thickness you could attach it and not have to worry a bit. But remember, you want to density of the hair unit to blend with your own sides and back (unless you're going with a full cap). You'd have to have good density on your sides and back to make a nice blend with the unit.
Regards,
John
