Have you considered 'Dednutz' one piece base & ring combo? Sounds good to me & would try a set if I were to get another rifle. You can find them at Natchez I'm sure. Maybe even Midsouth or Midway too.
I'm also interested in the Burris Tacticle Weaver style bases that has several slots for mounting differant style & eye relief of 'scopes. The Burris Signature Z rings are very nice, I do have these. The tac bases are kinda hard to find which tells me something.
