I've been out to this type of bowler more times than I care to remember. In fact if I see one come on I get a cold sweat! One of the hardest things is that you never get to practice against this type of bowling. I've seen better players than me take this bowling apart though, the two things I've seen these players do is,
1- move down the pitch and take the ball on the full. They don't try and over hit it though!
2- play the ball very, very late. Not plant your front foot and wait, which I normally do, but really wait until you commit yourself.
I still get out to these bowlers, so let me know if you have anymore ideas!!!!
Good luck.
