i'd like to see how a compound radius is done. i'm sure producing a diferent one wouldn't bee an easy task, and i agree with gregg, err somewhat. the diference between 7" and 9" is more notable than say maybe 9 and 12 and probably even 10 to 16 but really i can't think of an advantage over a straight radius. it's still not flat enough to help your bends a whole lot. i'm all for more options but is the money/effort worth the results? how many people will actually order it?
