Riving stock should be producing straight grained boards. I was under the impression that was the great benefit of riven stock. I like VG lumber a lot, basically the closest I can get to that ideal without felling trees myself.
Mike, a pair a winding stocks does not find the highs on an edge, it's used at the ends of the board to see if there is any 'wind' or twist to the face in question. It's the only way I'm aware of, other than using a known flat reference, to check for twist.
I do as Prashun does on small parts, using a section of my bench as a flat reference. For thin/ small pieces it is great.
If you have a few hours (or days) read through some of my blog posts as I routinely go over making original reference faces in rough sawn stock. The photo essays may help offer a new perspective.
