I've had pretty good luck transporting a real licking branch to a more desired location. Clip off a small section of an authentic scrape branch and zip tie it to a new branch in the location you want.
You are transporting the real deal. It has every odor on it that a real branch has because it IS the real thing.
Once bucks discover it, they will start to use it and it is no longer a mock scrape, it's now a real scrape.
I have not experimented with tying a real lick branch to a rope, but it's worth trying. It might be just the thing to get a finicky buck to accept it. Once they start using it because of the real buck odors, they will most likely continue utilizing it as just the rope. Transporting a clipped licking branch is a short term deal IME. The clipped branch tends to not be super durable and it gets torn down. But at that point, the anchor branch (or rope) will have become the new branch.
Obviously, handle the clipped branch with rubber gloves. I try to choose a branch to clip from the same property so I don't have to transport it in a vehicle. Not sure if it matters, but I really try to not contaminate it. I have transported them in garbage bags.
I sometimes take a little sample of scrape dirt, too.
Basically, I transport a scrape from a useless location to a desired location.
Once they use it, it then becomes the real thing.
