One interesting comment was that the quad powered DI had guardian mode issues in hard turns. Seems the 350 is still very sensitive to this.
Check out the weight on the DI

Overall I think the Sonics performance is pretty impressive for twins. They felt it would break 70mph with better conditions. Not enough fuel capacity for its size though. You could almost buy two though!
