You can try and pm milocoman here and see if they have any cf zen's in stock, they usually give members a great price. Cf8 and Xl1 would have to get from the bay as they are no longer produced. Combat maxum is also great bat.
My son uses -5 Demarini cf8 and it is the best bat I have seen around, ball flies off. A few kids on his team use the newer cf zen and it is just as hot. Easton xl1, orange one is very popular also, but endloaded and usually weighs a couple oz over.
