I think Hare's point is that since 2011 or so, the bats all have about the same max performance because they all have to meet the same exit speed parameters. There might be differences in sweet spot size, etc. but most of them are very similar and though the bat companies don't want you to know, there haven't been major changes the past few years. That also means that one companies bats don't perform much differently then anothers. It's really all about the paint job and which one feels better to your DD. There were many discussions on the Bucket about this back in that time period. Even had the head of Anderson Bat Company have a lengthy discussions about it all. So C77 saying the bats are hotter now than ever isn't quite true. They are actually not quite as hot as back in the late 00's, even less hot than the early 00's, (remember the original yellow Catalyst?) and haven't changed much for the last few years. Yes, the bats are still much better than back when we were growing up, but in fastpitch, in MY OPINIION, the thing that's changed the most is, there is a higher amount of athletes that are stronger and have better mechanics in the last 10 years.
Edited to add: The other thing that has changed at HS and below is when they moved the pitcher back 3 feet a few years ago. Elite pitchers can no longer just throw it by everyone. For this reason I don't think anyone will ever touch Dumezich's record of 489 K's in a season or 1651 in a career.
On a different topic, Anderson is a company you don't hear much about lately. They were a HeyBucket favorite for a while, probably because they were based in SoCal and even sponsered a few teams. You used to see quite a few RockeTechs out there at higher levels of travel, but not many any more. I looked at their website and they still offer a RT and was surprised to see they also had a composite fastpitch model.
