This is fantastic article and I am pretty sure cricket lovers will love this article. You are right-- ICC should frame and fix a rule of using this ball so that it becomes a benchmark for all the team to try their skill. Duke ball has more grip even after the 20/30 overs and hence swings more than kookaburra.
I am also resteeming it as I really loved reading this article.
Thanks for the kind words. I have played with both balls and I think they both offer different challenges for bowlers and batsmen.
