Yup James is right.
I was trying to find the pic that showed it clearly on merv.tv - I think it was a guy from menace that did it (dont hold me to it), but his pics dont appear to be working.
Its illegal as in, any modification that makes them different to how they were manufactured. Its illegal in all tournaments but it depends on the tournament as to how strict they are about these things. Even cutting the chin guard off a flex is actually illegal but hey..., Technically so is cutting the forehead protector off a flex 8.
vforce realised people were doing this and on the newer grillz they have indented that bit, i.e. there is a step in, if you get what i mean, it means that the section you want to cut off is still there to protect your ears however the main shape (the bit that you want) stands out.
