I have had no issue with mine and there are lots of people using them..
Good enough more lots of England players and county players.
I know plenty of people who really rate the shrey I personally like mine lighter and I believe scored as high as mauri on the safety tests.
But there bin lids so my knowledge is limited.
Safety test scores regarding concussion, Shrey gets nowhere near Masuri Vision Series. I cannot recall the units but its something like newtons per square inch, the allowed limit is 150. Masuri (last time i saw the data) is the only helmet with a sub 100 reading, Shrey is somewhere around the high 130's. Masuri are unhappy with their own numbers after Morgan suffered a minor concussion, hence the devlopment of their Poron XRD pro foams for added impact protection. Seen on the heads of many pros recently, look for the yellow ring under the peak that you can just about see on Billings helmet here.
I'm glad your helmet is OK, but please check under the ear foam where it meets the palstic, thats where i find most of the horrors.
Regarding what you've said about pro players. I suspect most have gone to Shrey for either the weight, or the money, or both. Some of course may simply prefer the fit of a Shrey. At the elite level the fitting issues will soon be non existent. Masuri have just developed 3D lazer head scanning technology to accurately map a players head and then build a helmet to shape to it perfectly. Morgan is currently wearing one after being the first head to be scanned in the Summer.
Regarding weight. The new Original Test helmets i have mentioned are about to launch. And will address all the problems that players have raised with the Vision Series regarding weight and looks, but unlike Shrey will actually be well built.
That leaves (in my opinion) the over riding reason for any professional to stick with Shrey as $$$$
I know you have mentioned in the past that you think Masuri pay players. All i can go in is the information they state both publicly and to trade customers, which is they do not pay any player to wear their product. Whether its true or not who knows. If they do pay then in my opinion it is obvious Shrey are paying more to certain pros, as there are fewer and fewer reasons to wear a Shrey aside from the cash.
