Whole heck of a lot of people who haven't even looked through the UHD's saying you're high. The UHD's are not the normal Razors. Here's a review from a direct comparison https://blog.sandsarchery.com/vortex-razor-uhd-10x42-review/ . Turn's out they too thought glassing in good light was better with the UHDs than the SLCs, giving the SLCs a slight edge during low light situations. That's a far cry from "not even close in low light". I'm a Swaro fan boy, but optically, the UHDs are no joke.
