Personally I twist it to help taper the end for ease to get it started in the coil, I untwist it a little to keep it from getting caught up between the wraps. If its too tight to pull
through, I remove some so it passes
through easily. Once I trim it up, I fluff it and tick it to the well on my origen clone.
Keeping it on the loose side makes it easier to remove when the wick needs to be replaced but not coil.
But in the end, it's all preference on what YOU like. Give both a try.
