Here are the tones (wave files) of 4 frames starting with the lowest toned Cross Trainer frame and ending with the highest toned M55 frame. You can compare your frame tone to these to see if your frame transmits lots of vibration into your feet and body or little vibration into your feet and body.
To test your frame take your frames off your boots and take the axles out and hang your frame by a piece of wire or string, then hit the frame with a piece of metal. If your frame tone is closer to the Cross Trainer tone then you have a frame that is better at dampening vibration for outdoor skating if the tone is nearer the M55 tone then you have a higher vibrating frame. (If you test your frame let me know so I can post the results.)
