Not sure what the discussion is here.
There a difference of opinions here. Is the Lax Helmet able to stop a softball? Some say yes, some say no. Should you were a chinstrap? Some say yes, some say no. Neither side is wrong, either way. it's all about what you believe and what you're comfortable with. Until someone takes a ball to the face mask, directly, we won't know.
I'm in the No chin strap, LAX group and nothing anyone can say will change my mind. Doesn't make me right, and doesn't make the non-believers wrong. I'm sure the people that use the strap or use the Worth mask or whatever, feel the same way about their decision. The horse is dead, stop hitting it, already. lol
