Pick the cord that sounds best, if its stiff, then pre-bend it into shape. I've found that this works great. Don't struggle with it, look at how you want it to go, then pre-bend it, then put it into place. I've had the VD Nite, Master and Revelation series. Yes they are stiff, but they sound very good, and when pre-bent there is not as much of a struggle.
