If you need a system that´ll last forever go with the medium skins, thick skins. But you need to wear bangs which suck bad when its windy outside. Which part of the world are you from? Forget about the 0,03mm skin if you want longevity.

Sebt: If you´r going to make a comparison its pretty critical to mention what kind of skin your wearing. It must be a medium skin unit around 0.1 mm from what you saying. There a 3-4 different kinds.
