What I found interesting in the article was the stage 3 and stage 4 info - and the types of bowlers that would FAVOR a ball in each stage.
I don't have the article with me (that's why I didn't supply details last night, either), but I think that this info would help us all figure out what we have, what we want, and what we're most comfortable with.
And - as an added bonus - if we adopt the 4 stage description here on ball reviews, when I list a ball for sale, I can state what stage the ball is currently in - that will give the potential buyer a LOT of information.
