Hi Ben - I'm really enjoying the Belly River. It's really perfect for doing small plein air pieces. I tried out the piggy back this afternoon, and took a few shots of my setup. The magnets are really handy for holding palette knives! I discovered it by accident when I was using a knife pretty close to the bottom support that holds the panel. I was about to lay in a small, straight line and the bracket grabbed the knife. Since then I just hang my palette knife from the magnets on the little door that folds down in front. Real handy.
