MAP steel rods

What is the opinion of MAP steel rods, Carrillo copies? The price is right. re balancing required?

This is not an answer to your question, but may lead to other responses related to your inquiry. Madass140 (Don Pender) also offers a steel rod for Nortons, and I know some of the builders here have used them, so they, or Don, might provide a response about that product. Below is a link to Don's website showing the rods and contact info if you have a question for Don about the rods. Also a link to a discussion of said rods.
