Our Dyneema Wishbones are nearly indestructable. We have both 2mm and 3mm Dyneema wishbones in the shop. The 3mm wishbones usually outlast the bands; we've never managed to break one. The 2mm wishbones are usually just as sturdy. We have single piece wishbones with a nice large knot tied on either end so you constrictor knot holds it without fail. We also sell loops so you create your own tie-in bands for guns with a closed bandslot. Just use a piece of reel line to bridge the gap and you are off and shooting!
