Yukon,
By the way, I once had a Siberian Husky named Yukon Jack. He was the best dog I've owned.
I just read an article about this problem and they fixed it with a drinking straw. They ran the leader from the swivel through a drinking straw cut to fit the length of line where it tied off to the weight. This kept it from tangling with the line during casts and drifts. Good luck and let me know if it works. I'll probably be trying it when the weather warms up.
