My rule of thumb that I use on my rba and others have put in here is twist the cotton and pull it through the coil so it only squeaks, not tugs the coil. When it is through pull it though back and forth a few times to make sure it is untwisted and fluffed. Cut the ends and fluff it out with a needle or the tweezers. With 60/40 you don't need to, but the "pancake method" works very well. Give it a shot. I use mine laying down on the couch and don't have any issues with it flooding... Granted I still get fluid under the drip tip after about 25% of the tank... but I hear that's normal.
