There's a sneaky little trick to straighten rolled-up tubing. Clamp one end of the roll in a vise, roll it out, and use a pair of vise grips, a come-along, and something rigid like the bumper of a car to put just a little stretch on the line. Don't overdo it, as you'll reduce the diameter of the line if you go too far, but it comes out arrow-straight with just an inch or two of stretch over the length of a 50-foot roll! Cut, bend, and flare the straightened line as required!
