The procedure is outlined here: http://www.stu-offroad.com/suspension/flaretool/ft-1.htm
The second picture on page two could pass for an ISO flare. As for reasons why to use direct ACVW replacement lines versus generic aftermarket lines? Well, they are much closer to the actual lengths you need. Other than that, generic aftermarket lines are only sold in specific lengths and you should always buy them in lengths longer than you need, but they have been installed in thousands of cars with no problems. As to the differences between single and double flares... an AN single flare has a 37 degree seat and uses a special coupler that doesn't exert any rotational force directly on the backside of the flare when tightening. A SAE double flare features a 45 degree seat and the material "folds back on top of itself", just as you described. A 37 degree AN fitting is superior, with nearly twice the clamping surface area of the 45 degree SAE double flare. The double flare was also intended for the assembly line rather than repeated field service, meaning that it doesn't seal very well after a few re&re's. An ISO flare looks more like a single "segment" of a bellows, getting larger in diameter before shrinking back to the starting diameter at the very tip.
