I am using Dutchware wasp on my ridgeline. I have them threaded into non-reflective gray zing-it. When I start to tighten down the ridgeline the wasp slips as I pull. I have to pinch down hard with my fingers to get it to hold. Once I wrap it around the front then pin it into the antenna it seems to stay but I haven't done anything more than practice in the backyard. I am concerned about the 'what if's' for my first hammock trip later next week. I have the little card Dutch sends and there isn't any rocket science in setting these up. Is it the cord I am using? Is this normal? I am not using a continuous ridgeline.

Thanks in advance for the feedback.
