How did you bend the tubing? I'm assuming frame mounted?
I don't think 7#'s is too bad, especially when you are enjoying all the light!
A friend of mine and I built a tubing bender rig out of plywood and an idler pulley. I called a tubing outfit in phoenix and they wanted $400.00 to bend the hoop for me, so we did it ourselves. Chrome moly tube is hard to bend. It took all day to get the hoops right.
