I don't buy into focusing on control in 10 and 12U will cause lack of velocity in your later years. Early focus should be on the girls learning the correct way to throw. Both control and velocity will come from consistency in proper mechanics.
Jim Kaat used to say he's take a pitcher throwing 85 over a "thrower" at 90. While those numbers are from baseball in the 80's there is truth in there. At some point the scale tips. Would you take a pitcher at 85 over a thrower at 100. Or in softball terms. a pitcher at 60 or a thrower at 70.
This video has been around before, but it is always a good watch.
