Bowling/Core Numbers
Expert: - 3/10/2008
QuestionThank you so much for your help. You have opened my eyes to alot of things but I have one more question I have for you. You was talking about core numbers. Can you please tell me what these numbers mean? I always see these numbers but could never understand what they mean. Also What kind of Rg numbers I should be looking for and what kind of Pin I should be looking for also. Also could you explain the Pin number. I always see 3 inch pin or 1 inch pin. Really dont know the difference.
As for the balls. You hit it on the head when you talked about the Storm ball you was talking about. My ball driller talked about it with me so I will get that but should I drill it for oil or for dry. What kind of pin should I get also? Any other recommendations for dry and Regular House shot? Thank you again so much.
AnswerRobert,
Simply, low Radius of Gyration (RG) numbers mean a ball able to change direction more readily. Higher numbers means a ball less likely to change direction readily.
Low RG more hook POTENTIAL. High RG longer, later, less.
Your specific needs must match up to your rev rate, ball speed, lane conditions, etc. Layouts too can take the greatest ball in the world for YOU and get it rolling too soon, or too late. The RG numbers of the Encore are 2.55. Red Alert 300 - 2.498.
Recollect all you equipment and determine why you liked it? Record the pros and cons, and more often the pin position that works good and/or the surface and/or the core dynamic numbers, etc. will start sticking out.
The pin number is the approximate distance from the pin (top of the weight block) to the center of gravity (cg). 3 inch pin is approximately 3 inches from the center of gravity.
Please don't spend a bunch of money on a high end ball and fight what it's made for. The Storm stuff I talked about are strong balls. You don't need a strong ball on dry lanes, unless you throw 25mph!!!! Which ball specifically did you discuss with your driller? The layout is better handled by him, but if you'd like discuss it and write me back. Good luck. Thanks for the questions.
