Fastpitch bats

Question
Hello. We have talked before reguarding my daughters pitching, but now i would like to find out about bats. I have researched bats online like CRAZY, and found that everyone says that their bat is the best. We live in Illinois and I am looking for a bat that has alot of pop in it. Meaning the ball flies off the bat. I want one that does not sting when you hit. There are so many out there. I have found 3 or 4 that I am interested in, but I want you opinon on them if you have one. The first bat is the Miken NRG 500 in a 33" 23ounce bat. Next is the Worth Mayhem. The Miken ICON is another one. And the last one is the Anderson TechZilla. Let me know what you think please.

Answer
i have heard that the TechZilla is a really good bat. but from my experience and from what i see many others use is a Catalyst. They do not sting at all. in fact when yo make contact with the ball it feels smooth. and trust me, if your daughter has a good swing the ball will FLY with this bat. but if you are going with one of the bats that you listed then go with the Techzilla!
