'Our goal is to find balance across varying conditions'
Brett Elliot, managing director of Kookaburra, opens up about the challenges facing the brand in facilitating an even playing field with the pink ball
The feedback was very positive. The players were happy with the balls and their performance. They felt the ball swung earlier on and didn't do much later on. That is reflective of what we also experienced with the pink ball. But the wear of the ball was very good. The players also felt the visibility of the ball was very good. This always will be a process of continual improvement. The process when you take the feedback of players and experts. You look at it and review it, and you continually try and refine the product at each stage.
The biggest challenge is the variation of pitch and playing conditions around the world. And not just from one country to the next, but even so much as one ground to the next. Increasingly we are seeing that the preparation of pitches is becoming much more scientific and therefore we are in situations where the ball might perform perfectly in one set of conditions, and then we go to a ground where a pitch has been prepared where any grass and moisture has been removed. In such conditions, a coloured ball will always suffer more than a red ball.
There were three pitches - one was left out from the World T20, one from the IPL. They were both without any grass cover, very dry, and were in a repaired state. We could not use them. The third pitch had about 3mm across it, not on all areas, but in some. Now I understand that is probably a lot of grass in India, and that is probably considered to be no grass in some other countries. Because we did not know how the ball would perform on a pitch without any grass, we did not want to subject the ball to the worst possible scenario [abrasive surface] and then risk it not working, or the ball deteriorating too quickly and then creating negativity towards the situation, which would have been unfair.
We are looking at making changes to the ball that would make it a little bit more suitable for spin bowling, a little bit more suitable for seam bowling, and the seam holds up a little bit longer. That is not hard for us to do, but what we don't want to do is make a radical change, and then all of a sudden change the characteristics and expectations in a game. We have to do these changes gradually and subtly and through a consultation process with the game's statekeholders.
You can change the construction of the core so that it is more conducive to spin bowling, by weighting the core more heavily in the middle. It has an effect like an ice skater on the rink: when she spins with her arms wide, she spins slowly, and as she brings her arms in, she accelerates. All she has done is bring her weight in, which has enabled her to spin faster. It's the same principle that applies with the Kookaburra centre versus Dukes, where we can vary it.
Yes, we did. We can increase the bulk of the seam very easily, and it is a very simple process.
The BCCI has been happy with the same thread that was used on the ball in the inaugural day-night Test in Adelaide. These balls have been used in practice and will be used in the Duleep Trophy.
Following some research and development trials we did in India, we did strengthen the finishes on the ball. So that has reduced the rate of deterioration of the ball. Those finishes effectively grab hold of the leather, and slow down the rate at which the ball wears and the leather is exposed. When that happens, it picks up the dirt, dust and muck from the surrounding conditions. As a consequence you get the discoloration, and that is when the visibility is affected. But that deterioration is also part of the game. So we have been adjusting how strong those finishes are to ensure we get a very even and controlled rate of deterioration.
If at 80 overs the ball still looks new then that is not good. What we don't want, though, is after ten overs we don't want the ball looking like it has been used for 80 overs. It is about that balance. So it might be two coats where it is a little bit stronger, and then two coats where it is softer again. And therefore what we create are layers of coating that are able to deteriorate at varying speeds. That is what we are exploring in our trials.
