I've got a good one for the contest which I picked up from an old timer at Barrier Dam. To add weight to your drift gear, or float set up just leave a little extra line after tying on your leader and crimp some hollow core on. The weight will pull off easy, or harder depending on how you crimp it. It makes adding/changing weight a snap without the snap swivel, surgical tubing, or parichute cord. I've had a lot of success with this. Hope it works for you too!
