critical. Specifically with CZP, don't they have a history of some sketchy practices? I remember seeing something about fuel rails once upon a time. I don't intend to completely railroad them, but these are the types of things to take into consideration when buying parts. To be fair, I've also been told by some to completely avoid Z1 and that they're clowns who don't know what they're doing, but aside from a mis-ship, I've had all positive experiences with them.
