From everything I've read and have learned first hand from trying them through DD, these are the hottest bats by manufacturer,
Anderson..either a Rocketech FP-9 or a Nanotech. Demarini...either a CF4 Insane or a CF5 Insane/Hope. Easton...Stealth. Lousville Slugger...Xeno. Miken...Freak. It all depends on whether you want end-loaded or a balanced bat so there are a mix of both in this list. My DD plays with the Anderson FP-9 and the Demarini CF4 Insane. They are both end-loaded bats and she loves them both. As far as the CF4 stinging your DD's hands, it's definitely cracked somewhere. Get rid of it and buy new. I think my DD will end up with the Miken Freak next
