This split works get! Its stays put on your leader, and it has a small notch on the back that makes it easy to remove. Its more expensive than some of the brands with the little ears on them but well worth the price.
Lead shot is pretty much the same from all vendors that I have used. However, their packaging is not. Thill's packaging is strong, and very easy to dispense just one piece of shot. I don't think I will have it spilling all over the floor or in my vest or stream bottom as other containers have.
