Point one:
Shrey have in my opinion (I could be wrong) the most popular helmet on the market albeit formally branded as Masuri. Clearly it has provided adequate protection more times than it has failed. The majority of cricketers in my opinion are both fussy and superstitious about their kit (including helmets) as a result I believe we will see the majority of international cricketers continue to use the current Shrey design. As a result the majority of customers will buy the helmet that their favourite players use which I believe will be Shrey (unless it is unavailable to the market).
Point two:
WE SHOULD ALL WANT HELMETS TO IMPROVE AND PROVIDE THE BEST PROTECTION IT CAN, after all a helmet is designed to protect you. We want players to continue playing even if they get hit on the head and on multiple occasions this has not been the case. There must be a reason for Masuri changing their helmets and I can only assume that it is to do with the grille (their new helmets seem to focus on this). I believe that Ayrtek have the best helmet in terms of protection on the market currently and I can only praise the company for producing a helmet with safety in mind and not focusing on aesthetics. Maybe I'm biased as I am from Bristol but I am NOT an Ayrtek user and in fact use my Masuri when I do use a helmet.
I think this is basically the argument that required 14 pages of largely nonsense.
From what I know (through this thread)
Shrey produce a copy of the Masuri helmet since they moved production back to the UK.
This is to the current standard and is a very good helmet.
There is a new standard coming in.
Some guy on here thinks Shrey are the best ever and won't change and won't bend to the new regulations and has a "what you going to do?" stance. He then says that thy are working to it and Shrey will be market leader and everyone will wear one.
End of the day, personal choice will prevail. There will always be choice and options. I don't even know whether Shrey have entered the UK market officially yet.
