I don't have any experience with the UUC poly as I have only used the UUC Black and Red Neoprene. The blacks did not introduce any noticeable NVH at all but the shifts felt more solid- I have installed these in my Z4M and my friend's E46 M3 with the same results.

I decided later to try the red Neoprene for a "little more" and found that if not installed perfect, meaning zero preload, there was some NVH. After some adjustments to get rid of the preload the NVH was still there but barely noticeable initially and even less so now.....maybe I'm used to it?

Both reds and blacks were installed with the enforcer cups although the cups needed a little tweaking to allow the zero preload condition. I'm not sure I would run cups if I had poly.

If I had to choose today I might go Rogue just because I think Neoprene is a better material for mounts for me. I may at some point upgrade the engine mounts to Rogue trying to get that "little more"
