The guy with the white chair does photograph both ends, so you can see what the spring/summer ratio is. You have to watch this, there is quite a bit of variability in what is for sale. You also need to watch out because the ends of some of the staves come from near the stump, and you can see bigger/thicker rings on this end but the other end might be more puny. I can usually tell which end is up on a stave, from a closeup of the rings on both ends. One of the best indicators that a stave is top notch that I've noticed, is that several people bid on it and the price goes over $50 pretty fast.
