I did a research paper for my marketing class and chose bowling balls. I did an interview with Riger Noordhook when he was with Storm and the Hy-Road was one of my subjects in my paper as to what determines when a ball is discontinued. He said they look at sales and have a number and when a ball falls below that number for the month, it will be put in the potential discontinued list. He said with the Hy-Road, every time it drops below, the following few months, sales increase and it get taken off list again. It was a great subject and appreciated the hour of his time he gave me on the phone. I was always curious as to one ball is around for 6-9 months, think it is great but is discontinued and then there is the Hy-Road which has seen a blessing to many bowlers (I did not match up well with it) and has been a great seller for me.
