The idea of 'bounce enhancing' masks however is that they're built with angles on them that make dead-on contact less likely. The more likely a shot is to catch the mask at an angle than straight on, the more likely it is to bounce. They do not sacrifice safety but rather try to make the contours on the masks more angular so the balls hit on angles always.
If you don't understand what I'm saying do a search for the A5 and X7 stock hoppers and look at the front (What you'd see if someone was shooting straight at you). The A5 is a big flat front, basically any ball that hits it will break because 90 degree contact will transfer ALL of the energy the ball has into impact. The X7 is extremely angular, the flat surface area is a fraction of the A5's. This way the same shot that would have broken on the A5 carelessly bounces off the X7, saving your elimination.
Ghillies aren't BDU's but I agree with the if it hits it counts whether it breaks or not since a ghillie creates more of a chance of a bounce than a BDU... to my knowledge anyways.
The thing about your way of portraying the idea of "bounce enhancing" masks is that you use the terms "bounce enhancing" to define the idea deflections while in reality they enhance bounces, thats why they attach that term to the masks... Deflections are different, you dont need soft rubber for a deflection, (it can happen with harder surfaces, Example: Hoppers like on the X7, Im pretty certain they are not a soft rubber, and my cousins skull last sunday, I got a bounce right off the top of his head (not the mask, his head)) but soft rubber just so happens to help a lot when it comes to bounces, and softening the blow of a paintball therefore lengthening the time it takes for the force to be released from the ball, and with the remaining force rather than break (because the force required for the break has been slowly destributed) just bounce off of the "bounce enhancing" mask.
And I understand what your saying, but deflections happen off of harder surfaces (as previously said stratigically angled hoppers), therefore soft rubber would not be needed for a mask, unless of course the soft rubber promotes the actual bouncing of a ball off of the mask, which it is advertised to do so... and isnt that a little odd considering the rules are not too kind to the idea of bounce enhancing clothing?
But your probably all sick of me poking at this. So I will leave my argument at that... Its odd... Hypocritcal if you will....
This is why I always paintball topless
