I seriously doubt I'd have noticed it in green. Slope of grain, especially what I'd call "local slope of grain" near joinery can be a biggie strengthwise. You know real quick with a drawknife, chisel or slick. Apologies to BB and Eric C, Derek's had the jukebox in my head singing "Riving with the King" all week laugh.

I would like to hear more on the righty lefty thing as anyone comes across it.
