Hi all, I'm in the process of putting my first hammock system together. I had planned on using dynaglide for the cont. RL and use prusik knots to tighten the tarp. After stringing up the RL in my back yard, I find the prusik won't hold. I used dynaglide and the reflective guy line off my tent as the cont loop for the prusik

Should I use something else for eithe RL or the prusik?

Thanks
