Right on. I tried the Nicop, Poly Armour, Edelman (Orielly's brand, coated like the Poly Armour) and regular steele brake tubing. Of all four I tried, the Nicop was by far the easiest to work with. The Poly Armour was more rigid than the Edelman and pretty close to the same as working with the regular steel brake tubing. Despite trying the different dies, I just couldn't get the consistency from the Craftsman tool. The tool itself is very well built and I decided to keep it around. If I ever needed to flare anything bigger than the 3/16" brake tubing, I will definitely give it a try. So far, the CTA inline flaring tool I got is flawless for the Nicop tubing in 3/16". I also had a thread up about all this not too long ago.
