I'll tell you one thing, I reckon every Aussie spinner looks at English pitches envious. I know I do.
I think the small grounds is an issue that doesn't help; young spinners can beat a batsman, have him miscue sixes quite easily, and you can't blame the captain for not keeping him on when it happens a number of times. If the boundary was bigger, he could have three fa. Plus the lack of bowling restrictions in many leagues, which can make the standard better, does encourage your medium pacers that can get through 15+ overs straight.
Those damp wickets allow the ball to turn, even if it is slow turn, and keeps the spinners in the game.
