Thanks! You are always more than helpful on this forum! I'd love to hear back when you know what yours was made of. Obviously it sounds like SFS is the most undetectable. But I don't want it to fall apart after a month. I don't have that kind of money. Haha.

Also, I've read a bit about trouble with ventilation on full caps. What would you suggest I specify when ordering to make sure the ventilation is right? I'm going for a hairstyle probably similar to this for my first one, I'm a little scared to expose too much as a newbie, and this is pretty much the style I have now. (I'll try to attach an image, haven't done it before so I'm sorry if it fails)
