My personal preference is a longer availability for the ball. by the time you've put the ball thru a reasonable number of conditions (within the parameters of use meant by the manufacturer), the ball is usually not being made anymore. for example, I got an obsession 2nd hand after trying it for about 2 months I'd decided it would be worth to make it the basis of a 3 ball arsenal for hi volume/long oil patterns. When I called the country distributor, he told me the ball had been discontinued. (I was able to get another one but at 15 lbs, I throw 16, so sometimes on heavy oil, I go thru the breakpoint I want) And that ball X is so much better than than ball..
which brings me to my 2nd comment... ok Ball 2 is so much better than ball one, but by how much..
But I guess this belong to another thread, and not limited to any one ball company.
sorry for the long post..
