What would you guys think is the toughest(most ridgid) rings (and best looking)?

My vote goes to Warne for being the strongest. Best looking is kind of subjective. The Leupold is finer and would look better on a smaller rifle but the Warne look just fine on heavier rifles.

Have used Warne and Leupold rings but feel that Burris Z rings are stronger than either. Perhaps not as "pretty" but definitely strong....and far cheaper!
