Warning, the tit rods are right on the edge of being too light. The coat hanger trick is really good. You get stakes that are lighter than the lightest tit stakes on the marker and they hold better. Making 'u' stakes from tit rod seems like the next step. Unfortunately, the size jumps from BPL's 1/16 to 1/8", and I doubt those would save much weight. However, there would be no question of their being strong enough.
