Forgive my noobness, as I am sure this is answered in-depth somewhere already, but I can't seem to find the answer. I have an EFX helmet too, and it says to make the helmet EI ready, it requires accurate mictips. So the mictips that come with the EFX are OK for approval, but not acceptable for EI? I can't really see any difference when I look at mine and other helmets that have earned EI, so I suppose I'm missing some obvious, small detail about it. If anybody can point me to a comparrison shot & a good source to get accurate mictips, I'd appreciate it. Also, I have my gaps filled in, lenses replaced, screws in ears, tube stripes replaced, and teeth holes added/widened, so now I'm trying to lock-down the mictip issue. Have I missed any other mod I need to do? Thanks!
