Well different people are throwing the ball first off. Clearly the nano was a hook monster when it came out...now every manufacturer has a "nano type reaction"...this is storms next rendition...staying ahead of the curve as some would say. Everything is relative. I see the two being similar... but with different motion in terms of hook shape. My sync covers more boards than my nano, but my sync is just more continuous, my nano gets a bit further down the lane before it transition..
There won't be much difference, same cover, different core.
