Add Sig Zulu 16x50 HDX Pro's to my kit??

I currently have a pair of the Zulu6 HDX Gen 2's in 10x30. I actually really like them, and mostly used for archery elk and midwest whitetail.
Does anyone also run the 16x50 HDX Pro's as part of their setup? We might be doing some more spot and stalk mule deer hunting as well as rifle elk in the future, and wondering if the 16x50's would be a good addition?

I run the 10 + 20 non pro. It's a good combo. I'd consider leaping to the 18x.
