Pros : I have only been involved with stained glass for a couple of years. My first couple of projects I used lead came. After using this spooled came it made it so much easier to cut, stretch and use than the lead came. It is easier to work with and less waste. I now have all the different sizes of spooled lead, so I can use whichever size I want. My husband took a lead pipe and put all my spools on it; makes it very easy to pull off the amount I want to stretch. I think it is less expensive than the boxed came, so if I mess up a piece I do not feel so bad. Highly recommend all spooled lead.
Cons : Wish the spools were labeled as it is hard to know one from another until I use one of the wrong one.
