Thanks for the suggestions. I looked at te Wabi. From the reviews, most say that it rides likes steel? That's what I want to get away from. I need stiff and light. Which also throws out Leader frames, as they're 4+ lbs (let me know if I'm mistaken).

Looks like I don't have many choices. Maybe I'll try to make the Cinelli Vig work. Or look into Felt/Trek/Cannondale frames as well.
