X2 on the Hutchinson style (Hummer) double bead locks if you want double locks. I've helped a few friends with Stauns over the years and while my experiences weren't quite as terrible as Yeller's, they were a challenge both initially and then repeatedly thereafter with respect to maintenance and reliability. I love the concept, but the reality certainly didn't live up to the hype. FWIW, I helped my brother assemble some Ø20" Hutchinsons with some Michelen XZL Ø53" tires for his Axeltechs, and aside from requiring a bit of brute force with a 300# tire, it actually wasn't too bad for a couple of guys on a Saturday, so I can only imagine something smaller/lighter would be a bit less strenuous.
Stazworks could be a good option if you're not loving the Hutchinsons or need a full custom option.
