I am using the HF elliptical coil on my ORX and find it to be extremely lightweight and perfectly balanced. Thinking about getting the 9" X35 coil and would like to know how it compares to the HF elliptical as far as weight and balance are concerned. Please don't post about the differences in performance, JUST weight and balance. If you are using both or have used both, I'd be interested in hearing from you. Thanks
