I agree. I've been experimenting with an adjustable (short) bungee that I can make very tight, medium tight, or even loose if needed. (Home Depot) Working pretty well. I currently have them on a double half-lock but may later separate them because the tension on the short and long are always the same. I tried the swivel technique to adjust the tension and just could not make it work the way I wanted but probably just something I wasn't doing right. Good thread to see different points of views and techiques.Not only is the mono hard to grip but tension is the key however, simply being tight is not enough. I believe it is critical to be able to vary the tension on each individual halyard because different lures run differently under different tensions and different sea conditions. Nylon cord offers this ability simply by employing a swivel on the halyard.
