I used a combination of OneTab, The Great Suspender, and Evernote. I let The Great Suspender keep my memory footprint down but every week or so I scan through my tabs and throw as many as I can into Evernote with tags. Anything left over I can generate a OneTab page and Evernote that whole page of links at once.

I tried that one, and it is indeed good, but see my other reply about how spacial organization works best for me. One Tab just didn't hit the sweet spot my normal system achieves, again, for me.
