I just went on their website and see they now ask you to specify size (under 14, 14-17, and over 17) They also now charge accordingly.
I see the price has gone up a bit since the summer. Used to be only one size to order for $58 plus shipping, and they usually ranged between 14 and 17 pounds when I received them.
I have been very satisfied with the ones I've gotten. With the price increase, I think I'll try the under 14lbs next.
