I use all French lace, I tried Swiss and had them tear or get a hole. The French to me is almost exactly the same but stronger, last longer.... I go a slightly lower density, wich shows a realistic scalp if you part your hair. I have noticed that thes things look thicker on your head than in your hand or or on a wig stand, I don't know if its just me but I have gotten some that seemed to thinn and the POOF on my head they were quite thick and I thined them a little....
