Since rift sawn I essentially cut radially to the center line of the trunk, I would think the grain would be more balanced on both sides of the blank but less figure than quarter sawn.
The pictures may have their captions reversed? I believed logs are rift sawn for some quartersawn look, but otherise for maximum yeild. True quarter sawed logs require a bunch of loss in the form of triangular off cuts.
Keith, I'll look back at why I'm thinking different, but I have always known rift sawn boards to show angular grain orientation when looking at the end grain. While quater sawn shows ninety degrees to the face of a board when looking at the end grain?
I believe plain sawn material ends up with the fewest growth rings around the action inletting, the easiest chance of grain running off the direction of the stock, and has the highest chance of looking like plywood.
