I've been training, 65-75 mpw, and racing in the Hyperspeed 2 for the last 9 months or so. Come year end, the 2 will be replaced with the 3. Not a huge deal, but the 3 will have the new "rice husk" sole we've heard about. I'm wondering if anyone has any ideas of how this might change the feel, durability, etc? If not specific ideas, will it be an overall positive/negative change?
