Okay here is what I know about the SSR4.
It takes longer to break in than a SSR2 but way less time than a pre abi like the SCN9. It will eventually break in but it is more durable than a SSR2 so naturally it takes longer to get to it's full potential. Once it is fully broken in and started to spiral web a bit it will keep up with any other post abi out there. It is a 2 piece obviously but they do not ever click or wobble like a SCN5,9,or7. It is a balanced bat that leans slightly towards the EL side if measured exactly. That is normal for all Easton's 2 piece large barrel bats. Performance wise though it is very comparable to anything else Easton has put out post abi. The sweet spot is not just at the end, unless that is the only area you break in. Just like all of Easton's big barrels, the SS is big too. I will agree with Jakeski13 that it has a softer feel, but only when compared to Easton. It will never get as soft as a Demarini or Miken.....if you like that sort of thing. Personally, I like the feedback because it tells me when I'm off. I don't want to feel like I got all of it everytime only to see poor results. At least with a stiffer barrel I know by the feedback, or lack there of, how well I am actually striking the ball. Did I miss anything?
