Pros These are fine basic brushes. They distribute the flux well and they are nicely inexpensive.
Cons Little hairs from the brush come out and get stuck in my flux, requiring me to pick them out so they don't get stuck in the solder bead. It doesn't take long to destroy them - at least the way I use them.
Pros The flow is nice, but what I really appreciate about it is how pure the alloy is. It makes cleaner solder seams than any other I've tried.
Cons It's more expensive, but I tried other stuff and was very disappointed.
Other Thoughts If you are going to patina black, it may not matter as much, but when I am going to leave the solder silver, as I do on much of my work, I use this solder for a clean and smooth bead.
