Re: Double Haul.... Won't.....
It's new rod but I would still check every one of the line guides to make sure one of them has not been nicked.
Another possibility is that some rods do not have a smooth surface but still have the pressure ridges from the curing wraps. This is true in some of the cheaper rods. They do not go to the expense of sanding and coating the rod. Line rubbing against these ridges could cause a zinging sound during line shoot.
I would also treat the line with a line dressing to see if that helps. I'm at a loss to explain the noise otherwise.
