Spinner Bowl

Question
I am bowling helicopter style. If you could help me I would like to get the right way buying bowling ball and how to give the impact when bowl as i always miss out 1 pin.

Thank you.

Answer
Natasya,
The helicopter style was developed for dramatically dry lanes. If lanes are conditioned normally (to protect them), the style is very difficult to control. There are no magic bowling balls. If you can not control your delivery, a bowling ball is not the answer. Helicopter players use very light bowling balls to gain ball speed. Light bowling balls contain less core dynamics (because of light or minimal cores).

What weight ball do you roll now? What do you average? Please let me know more. Thanks.
