This ball is awesome. My first 3 game series was 672.
I had previously bowled with an old sledge hammer, not getting much hook at all. The better reaction at the back end will help me to improve on my striking ability.
It picks up a lot of oil, and has discoloured after just 3 games. However, I am told that leaving it in hot water for 30 minutes will take out the oil, and rejuvenate it.
Looking forward to many more great games with this one.
Cheers
