I have an extended I will trade for either of the 28 oz 454 Mutants if you are interested. He said it was a 30oz but the sticker at the end of the bat fell off. I have swung it about 50 swings and it doesn't feel like it is broken in, but it looks like he took the clear coat off of it and our league will not let me swing it so it just sits in the closet. Not sure how many swings he put on it but I don't think many because it doesn't feel broken in, but like I said it looks like he took the clear coat off of it.
