If I can't find decent vertical grain WRC, I just go to the box stores or the local lumberyard and find clear 4X4 cedar fence posts with tight grain. You then cut one or (maybe) two GP paddle blanks, orienting the cuts so that you have vertical grain.
For smaller lumber, if you have ample free time, you can almost always find a piece of great vertical grain hiding amongst the junk boards.
Of course, there's a difference between needing a board or two for personal use, and someone who demands a constant supply for commercial purposes.
