You know what dino. I always used to grab samples of everything, and I never was impressed with any skin samples. They always looked like plastic or something on my skin. But i have to admit BA was right. Until you get a system and attach it with glue to your scalp, you wont know as well. Now the thin skin units seem pretty nice to me. I just wouldnt like it for the reason u mentioned above with the heat. So i figure why not get a lace center and skin perimeter? that way you can have both.
