I’ve used several pairs of both the Signature Zee rings (sleek and low drag hunting rings) and XTR Signature rings (bulky and robust tactical rings). Both are great for their purposes. I do prefer an angled rail and a conventional ring design better, but occasionally angled bases are not available, or I want to maximize the potential utility my optic’s elevator, so I’ll put adjustable or angled rings on top of an angled rail.
