I'm not 100 per cent sure but I'm pretty sure none are adjustable and that's what's causing the issue. cook ,Compton ,trott don't like them because they cannot sight the ball property-just about the most important part of batting.
I've said before I think this whole thing is just wrong, Cook is the best person to decide what lid he wears.there is a risk in any sport....there's less risk of getting a ball thru the gap with the new ones, more risk of getting hit if you cannot sight the ball properly. Both have risk.....
Cook can't win sometimes, especially on this forum, he wears this lid because the Ecb say so against his better judgement or he wears the lid he thinks is best,for whatever reason, and gets stick for not setting an example and toeing the party line.
It's common knowledge he is a stubborn so and so. If you are going to get stick you might as well do it your way...
