Not sure when the M-Rocks were released, but have any of you done a side-by-side comparison of the Mantras and M-Rocks? Dimensions are nearly identical. I'm told the M-Rocks were designed to be a more AT-friendly version of the Mantras. I haven't seen a weight for the Mantras anywhere, although I'm sure they are heavier. I was curious as to the performance comparisons...
