Don't be such a gorilla changing them out! Never had a problem myself and have changed my clear and mirrored back and forth a lot. Both of my shields are oem Scorpion units, don't know if that makes a difference.They are a good entry level helmet. Moderately priced and fairly well built. I personally hate there visor mechanism. I've broken two shields with normal use.
700 is kinda heavy..
I bought the 700 earlier this year from newenough.com and it's a very good helmet.
Only thing I don't like is that the strap has a standard D buckle. Would much rather have the seat belt type latch like the one on my very worn out Bieffe GPR.
you can buy that buckle attachment for around $7 on ebay or cycle gear or anywhere. they're know to "snap" under stress is why most helmets dont come with them anymore.
Thinking about retiring my 400 this year in favor of this badboy!
