yey/ney. the yanks have higher fps limits. then again, some china mesh is lower quality. my mesh have been hit at point blank and it only have a small dent. some argue that paint coming of when shot can injure the eye, some (Ian) argue that it wont (after looking at some eye specialists video, I'd tend to agree). but it's our eyes after all, so may not be worth any risk or speculation either. hence I run plastic goggles with mesh lower.
only need to happen once. a friend of mine always use full face protection, except for that once when he lent it out and used goggles only.. that once that he got his tooth shot out.
