I have only ever been 'grilled' once, it was off a medium pace bowler and i was keeping and standing up to the stumps...
as a very inexperienced keeper who is usually a quicky, i took my eyes of a ball that was edged off a cow corner slog and it hit me flush on the grill.
From what i experienced the ball defo accelerated off the bat and came at me alot quicker than i expected...
I have the grille on the setting that shouldn't allow the ball through and it didn't come through, i use the Masuri that Kieswetter was wearing and it hasnt really put me off. However the fact a helmet that apparently is up to the new standards has failed has made me want to upgrade to the new Masuri...
Please Ollie, you're just looking for an excuse to flash that new debit card of yours. I got grilled off a top edge pull in the old Masuri (before the sweeping grill) and I was fine. At our level you will be fine. Think off the 2 people you have hit in the helmet this year, wearing a GN and a Woodworm, they were fine.
Plus that new Masuri is packing some serious weight!
