I have not tried Warne bases. My experience with them is the rings that work directly with CZs, their Ruger #1 offering, and the weaver/pic combo style I've used on crossbows.
I am aware of your solution, moving rings opposing directions to create minimal play between them. It isn't an ideal solution, its introducing stress because the back of the scope is being pushed forward under recoil and it has no forward support.
To avoid these problems, I just pay the piper and go with Talleys. $135 for QD w/ levers, their bases are excellent and around $26. You're paying a little bit more, but they are a better product. They also offer a vintage style ring that uses one screw for that european look, and their magnum style that uses two screws per side.
I know you're a frugal hunter, but I do believe you'd find satisfaction spending the extra $55 for Talleys. The next better ring than the Talleys is in that $500-$600 price point, a big leap. (and that's an EAW assuming you can design/build/install them yourself, most people cannot)
