IMO, the single most important factor in hitting success - at any level - is the athletic ability to get the bat on the ball. Those who can do it with speed, suddenness, and adjustabilty will have great success.
If you think the softball world has idealized the high-level swing, be grateful for your coaches. I could cover the walls of my garage with quotes from coaches trying to "fix" DD's swing the last 2 years.
Lots of bats were grandfathered when ABI began. The "hot bat" era didn't end until 2011 when NCAA instituted BCT and their own approved bat list.Several factors worth considering IMO
1. Does anyone have (or care to put together) HR/year pre- versus post-2008, when ABI went into effect and officially ended the true "hot bat" era.
