Thank you for the response John.

So I can't have a base undetectable to touch and good for sports? Does poly feel like plastic? Would I have to have two bases, one just for sports?

Correct me if I'm wrong but from the base options I understand that the swiss is the most undetectable, french is a stronger more durable lace to protect hair from falling out, but what makes it more detectable than the swiss and how much more detectable? Ilace is two layers of lace for extra strength against hair falling out, but is it undetectable like the swiss? TL500 offers the best undetectability in the front, but strength in the middle. The Ilace and TL500 seem like the best options for both undetectability and strength against hair fall out, with Ilace being stronger, and 500 being more undetectable because of one layer of lace. If thats true than the 500 seems like the smartest option, depending on ofcourse how detectable the french lace part is.

Also some things I forgot to ask, what are the "clips" mentioned in the attaching tutorial, are they metal pieces or something that can be felt?
How exactly are hairpieces removed?
