I've got to say your experience is totally different than mine. My race rods weight 78 grams. My diamond frames come in at fifty grams. Significantly less. I have flown Precision competition at 2-3 mph wind and scored very well when others could barely get their kites in the air. We have four sets now. Like them a lot. They also perform very well in a mid vent kite if you want the added stability of a mid but the winds are light.
I just received mine but have not used them. Maybe Ben can shed some light on the weight. Ragin Cajun has the new Diamonds @59.5 grams and his Orig Race Rods at 58.4 grams. Whereas Cass said his original Race Rods weigh in @78 grams. I am sure Ben or Lolly could shed some light on the discrepancy in weight between the two different rods.
