So I have another pitching DD dilemma:
DD has a CU that is 15mph slower than her FB.
DD has an "off-speed" (remember, just names now...) that is 7-10mph slower than fastball.
Which one is more effective at the 16U level?
My personal opinion is that the CU can be re-loaded to easy by good batters. But the CU will get the best "whiff" by a lesser batter. The Off-Speed will get the good batter to hit off-balance more.
I look forward to your experienced insights.
