OK, here it is.
The beads are made of hematite which is a mineral and basically iron ore. Interesting thing is it is a form of iron oxide but yet isn't what we would refer to as rust.
I don't have a weight yet, but it does have a nice "heft" to it which should help in casting and getting it down into the strike zone.
Only change I am going to make is going with smaller hooks (bronze colored). I like the idea of the red trebles but they are a little big in my opinion.
