Armour is as much in the mounting as the strength of the armour itself. Also depends on the type and the function of the armour. It may be thin and designed to flex deliberately, absorbing impacts, or it may be thick with the intention of simply keeping out the hits.

For Tormenta 2 we will be using a combination of 6mm and 10mm HDPE. Judging by our experience at the champs with v1, it should be fine. And, the beauty of it is, if it isn't, it won't cost an arm to buy more.
