Ok so I received my 27 oz aftermath USA today and it scales 26.5 oz and I re weighed the 28 oz and it scales at 27.1 oz. my 27 arrived with the weight sticker missing so since I'm ocd I called demarini to mail me one out. While on the phone I decided to bs about this weight thing with the rep being he was different than the last rep I spoke to.
He told me there is a 5 degree allowance in variance since the bats are hand made. So he stated there could be a variation of up to 2 oz of actual weight if you compare a group of the same bats labelled the same weight. 2 oz seams extreme and unlikely but I understood what he was getting at. Take my 28 oz that scaled around 27 oz so when tested it was slightly to heavy to be labelled 27 oz so it's on the lighter side of the 28 oz group. My 27 oz that scales only a half ounce less would be on the heavier side of the 27 oz group but there could very well be a labelled 27 oz of the same bat that actually only scales say 25.5 oz cause when tested its to heavy to be labelled 26 oz. He also swears even though it seams like a wide variation in weight that all bats that are labelled the same weight would feel and perform the same presuming one wasn't mislabeled.
So now I know my 27 oz juggy that scales at 25.1 oz the last I checked must be on the very lite side of the 27 oz labelled juggies but was deemed to heavy to be labelled a 26 oz. Hopefully I get one back that's closer to 26 oz scale weight and swings truer to 27 oz. Though if you think about it, it seams like if you swing both 26 and 27 oz bats and wanted one of each of the same bat for any reason that you could end up with two different labelled bats but they could almost weight practically the same like my two aftermaths.
