Problem with wishbones
Hi, I have been using these Cressi wishbones as shown in the picture, but when I load my speargun, they slide out after a few seconds. I have used two different types of constrictor knots—one learned from Daniel Mann and the other from Rob Allen. For tightening, I used 2mm braided nylon rope, and I tightened it as strongly as possible. What is the problem?
