I would like to put poly on our 883,just for the weight savings. That, and the old snouts are starting to come apart, most of the hinges aren't so good anymore. I haven't ever talked to anybody who put poly on, whatever color head, that regretted it. As to the slow down kit. I don't think I'd want the gathering chains any slower. In real good corn, it can't hardly clear everything out anyway. Chads
