Up until now, all the hair systems I've worn have been all Swiss lace systems. I'm thinking of trying a Swiss lace system with either skin or PU on the front/hairline. How does PU compare to skin for realism? I don't expose all my hairline, but I do wear my hair in a central parting since it's a bit longer (around 10 inches). It's mostly ok with Swiss lace, but I'm thinking the front of the parting that's exposed will look less detectable with either skin or PU. I tape the Swiss lace system all round usually, except for the very front of the parting, which I use glue on because otherwise the tape shines through (I even tried 'no shine' tape and it wasn't that great - glue is better at the exposed bit).
