I have had issues with some of the loop material I put on my Guardian as well. I dont think it has anything to do with the bow tho. If you are getting that thicker camo string put on it will spin all day long on my bow. That stuff is worthless. It is too thick and doesnt sinch down well enough. I use the stuff Gibblet sells , and it works really well. I'm not sure what that material is. A guy at the shop here put some wax on my loop material before he tied it and he said it would sinch it down better.
